Syntax
acuTrans [options]
Type
AcuSolve Post-Processing Program
Description
The results of AcuSolve are stored using an internal format in a number of files in the directory specified by the working_directory option (ACUSIM.DIR by defaults) and in binary by default. AcuTrans is used to gather and translate these results into various formats more suited for post-processing or visualizing by third party products.
In the following, the full name of each option is followed by its abbreviated name and its type. For a general description of option specifications, see Command Line Options and Configuration Files. See below for more individual option details:
- help or h (boolean)
- If set, the program prints a usage message and exits. The usage message includes all available options, their current values and the place where each option is set.
- problem or pb (string)
- The name of the problem is specified via this option. This name is used to build internal file names and to generate output files. All generated output files start with the problem name.
- working_directory or dir (string)
- All internal files are stored in this directory. This directory does not need to be on the same file system as the input files of the problem.

- time_steps or ts (string)
- Comma-separated list of time steps to be translated. The comma-separated fields have the general
range format beg:end:inc, where :end:inc and
:inc are optional. beg specifies the first
time step in the range. It may be either a given time step, as specified by
a number, the letter F (or f) requesting the first available time step, or
the letter L (or l) requesting the last available time step. end is the last
time step in the range. It may be either a time step number or L (or l)
requesting the last available time step. If end is missing,
the range is assumed to simply represent a single time step, that is,
end=beg and inc=1. inc is the increment that ranges from beg
to end. It may be either a number or the letter A (or a)
requesting all available time steps in the range. If :inc is
missing, it is assumed to be one. The range may also be specified by the
single letter A (or a), requesting all available time steps. This is
equivalent to F:L:A. time_steps is used only for nodal
data and is ignored for time series data. Examples of
time_steps option include:
acuTrans -ts 35 # step 35 acuTrans -ts 35,33,37 # steps 33, 35, and 37 acuTrans -ts 33:37:2 # steps 33, 35, and 37 acuTrans -ts 35,33:37:2,37 # steps 33, 35, and 37 acuTrans -ts 33:37 # all steps from 33 to 37 acuTrans -ts 33:37:A # available steps from 33 to 37 acuTrans -ts F:L:A # all available steps acuTrans -ts A # all available steps
- optimization_case_time_steps or cts (string)
- Comma-separated list of optimization case time steps to be translated. The comma-separated fields have the general range format beg:end:inc, where :end:inc and :inc are optional. beg specifies the first time step in the range. It may be either a given time step, as specified by a number, the letter F, or f, requesting the first available time step, or the letter L (or l) requesting the last available time step. end is the last time step in the range. It may be either a time step number or L (or l) requesting the last available time step. If end is missing, the range is assumed to simply represent a single time step, that is, end=beg and inc=1. inc is the increment that ranges from beg to end. It may be either a number or the letter A (or a) requesting all available time steps in the range. If :inc is missing, it is assumed to be one. The range may also be specified by the single letter A (or a), requesting all available time steps. This is equivalent to F:L:A.
- optimization_case or case (string)
- Comma-separated list of optimization cases to be translated.
- additional_runs or runs (string)
- Comma-separated list of runs to be translated. These are in addition to the main run given by
run_id. Additional runs not compatible with the
main are ignored. Combining four runs may be accomplished
by:
acuTrans -run 1 -runs "2,3,4"
- ignore_missing_steps or imts (boolean)
- If set, missing requested time steps are ignored. Otherwise, if the requested time step does not exist, the command issues an error message and exits.
- ignore_missing_cases or imcs (boolean)
- If set, missing requested optimization cases are ignored. Otherwise, if the requested optimization case does not exist, the command issues an error message and exits.
- ignore_missing_runs or imruns (boolean)
- If set, missing runs are ignored. Otherwise, if the requested run does not exist, the command issues an error message and exits. This option is used with the -runs command line option.
- ignore_missing_variables or imv (boolean)
- If set, missing requested variables are ignored. Otherwise, if the requested variable does not exist, the command issues an error message and exits.
- ignore_zeros or iz (boolean)
- If set, ignore zeros when computing statistics, that is, when using -to stats. This option is usually used for variables that are defined only on surfaces. See extended_nodal_output.
- mesh_output or mesh (boolean)
- If set, the problem mesh is translated. This option is valid with translation formats ideas, spectrum, EnSight, H3D, FieldView and actran. Note that the CGNS formats always receive the mesh. When converting to FieldView and fvopt is set to single, the mesh is always translated.
- remove_duplicate_surfaces or rmds (boolean)
- If set, all surfaces are checked for uniqueness before being written into the CGNS, FieldView, EnSight, or H3D file. This prevents surfaces that are utilized multiple times in the input file for SIMPLE_BOUNDARY_CONDITION, SURFACE_OUTPUT, or ELEMENT_BOUNDARY_CONDITION commands from appearing multiple times in output files. This option reduces the size of output files and eliminates redundant boundary definitions. The option is on by default. You can recover pre-V12.0 behavior in AcuTrans by turning this option off.
- mesh_movement or ale (boolean)
- If set, output deformed coordinates for mesh_output. Otherwise, output the reference coordinates.
- deformed_crd_type or defcrd (enumerated)
- This option controls which displacement field is written to the
mesh_displacement variable in all output types.
- midstep
- Write the mesh displacement field that corresponds to the displacement at the mid point of each time step. This option is useful when investigating the flow across non-conformal interfaces. The mid point of each time step is where the solution across the non-conformal interface is actually satisfied and should be visualized in order to see continuous contours across it. However, the boundary displacements for prescribed motions will also be written at the mid step and may not agree with the expectations based on input settings.
- endstep
- Write the mesh displacement field that corresponds to the displacement at the end point of each time step. This option produces a displacement field that aligns with the requested boundary displacements at each step, but does not correspond to the mesh displacement field that satisfies the governing equations. To visualize the mesh on which the governing equations are satisfied, use midstep. In practice, there is little use in this if there are no non-conformal interfaces present in the simulation and visualizing the solution on the mesh with the expected boundary displacements is preferred.
- nodal_output or out (boolean)
- If set, the nodal output, as specified by the NODAL_OUTPUT command in the input file, is translated. This option is valid with all translation formats.
- nodal_output_vars or outv (string)
- Comma-separated list of nodal_output variables to be
translated. The list may include:
where nSpecs is the number of species as given in the EQUATION command in the input file. Note that the problem must contain the requested variable in order for it to be translated. For example, the parameter turbulence in the EQUATION command must be set to a value other than none in order for eddy_viscosity to be available. The list of variables is sorted in the order given in the above table. If nodal_output_vars is set to _all, all available variables are translated. The surface_y_plus, surface_film_coefficient and wall_shear_stress are non-zero only on surface nodes given by TURBULENCE_WALL, or alternatively by SIMPLE_BOUNDARY_CONDITION of type wall. Note that the surface_film_coefficient is computed even if there is no temperature equation. However, all relevant fluid material models must include specific heat and conductivity models. It should also be noted that eddy_frequency and sqrt_eddy_period only appear when using the k-omega turbulence models. The dissipation_rate variable only appears when using the k-epsilon based turbulence models, and intermittency and transition_re_theta only appear when using the turbulence transition models.

Info Format
For info format, AcuTrans prints information about all the available time steps and variables.
Table Format
For table format, AcuTrans generates a number of output files, each containing a two-dimensional array of data. In the following problem is given by problem and step is the time step.
nodal output:
acuTrans -pb channel -out -outv pres,node,vel -ts 10
acuTrans -pb channel -out -extout -to stats
acuTrans -pb channel -out -extout -outv pres,node,vel,oqf_heat -ts 10
running_average_output
acuTrans -pb channel -ora -orav pres,node,vel -ts 10
creates the file channel_step10.ora, which has 5 columns corresponding to node_id, x_velocity, y_velocity, z_velocity, and pressure.
time_average_output
The time averaged output of a given time step is written as a two dimensional table in an output file named problem_stepstep.ota. The rows of the table correspond to the coordinate node numbers, written in the same order given by the COORDINATE command in the input file. The columns correspond to the translated data, in the order given in the time_average_output_vars table. Each data type occupies one or more columns, as given in the Fields column of the above table.
derived_quantity_output
The derived quantity output of a given time step is written as a two dimensional table in an output file named problem_stepstep.odq. The rows of the table correspond to the coordinate node numbers, written in the same order given by the COORDINATE command in the input file. The columns correspond to the translated data, in the order given in the derived_quantity_output_vars table. Each data type occupies one or more columns, as given in the Fields column of the above table.
surface_output
The nodal values of a given surface output set and a given time step are written as a two dimensional table in an output file named problem_srfsrf_stepstep.osf, where srf is a surface ID, starting from one, corresponding to each SURFACE_OUTPUT command in the order given in the input file. The rows of the tables correspond to all the nodes of the surface, numerically sorted. The columns correspond to the translated data, in the order given in the surface_output_vars table. Each data type occupies one or more columns, as given in the Fields column of the above table. For example, assume that "wall surface" is the second SURFACE_OUTPUT command in the input file, then
acuTrans -pb channel -osf -osfs "wall surface" -ts 10
creates the file channel_srf2_step10.osf containing all the output data available for surface output. The definitions of the surface output variables are given by the integrands of the surface_integral_output table below.
surface_integral_output
The integrated results of a given surface output set are written as a two-dimensional table in an output file named problem_srf.osi, where srf is a surface ID, starting from one, corresponding to each SURFACE_OUTPUT command in the order given in the input file. The rows of the tables correspond to all the available time steps. The columns correspond to the translated data, in the order given in the surface_integral_output_vars table. Each data type occupies one or more columns, as given in the Fields column of the above table. For example, assume that "wall -surface" is the second SURFACE_OUTPUT command in the input file, then

Stats format
For stats format, AcuTrans computes and prints the minimum, maximum and average of each data field. For nodal_output, running_average_output,time_average_output, derived_quantity_output, surface_output, output_radiation_surface, output_solar_radiation_surface, aero_acoustic_output, output_nodal_residual, output_error_estimator, and time_average_error_estimator the statistics are gathered over the number of nodes; and for surface_integral_output, surface_statistics_output, output_radiation_integral,output_solar_radiation_integral, element_integral_output,time_history_output, fan_component_output, and heat_exchanger_component_output the statistics are gathered over the available time steps. For example, the channel problem
acuTrans -verbose 1 -osf -to stats
acuTrans: Problem = channel
acuTrans: Run = 1
acuTrans: Translation format = stats
acuTrans: Translate to stats = surface output
acuTrans: Surface name = wall surface
acuTrans: Surface ID = 0
acuTrans: Surface output vars = node_id,mass_flux,momentum_flux,traction
acuTrans: Process time step = 5
acuTrans: Variable
acuTrans: mass_flux
acuTrans: x_momentum_flux
acuTrans: y_momentum_flux
acuTrans: z_momentum_flux
acuTrans: x_traction
acuTrans: y_traction
acuTrans: z_traction
acuTrans: Total CPU/Elapse time = 2.000000e-02 3.431511e-02 Sec
acuTrans: Total Memory Usage = 3.222275e-02 Mbytes
When computing statistics of variables not defined everywhere, usually those associated with extended_nodal_output, see nodal_output above, it is often useful to also specify ignore_zeros. The statistics will then be taken only over those nodes with non-zero values.
CGNS Format
acuTrans -out -to cgns
creates the database file channel.cgns.
FieldView Format
For FieldView format, AcuTrans translates the output data to a FieldView unstructured binary file, formats 2.4 or 2.7. FieldView is a visualization package distributed by Intelligent Light. See www.ilight.com. If fieldview_options option is set to classical, the nodal_output results of each time step along with the nodal coordinates, element connectivity and all surface definitions are written to files named problem_stepstep.fv. The surface definitions of each ELEMENT_BOUNDARY_CONDITION command are written under the FieldView boundary surface name "EBC: name", where name is the name of the set. Similarly the surface definitions of each SIMPLE_BOUNDARY_CONDITION, PARTICLE_SURFACE, SURFACE_OUTPUT, and TURBULENCE_WALL command are written under the FieldView boundary surface name "CBC: name", "PSF: name", "OSF: name", and "TWS: name", respectively. A FieldView region file named problem_stepstep.fv.fvreg is also created for each step that is translated. For example, the channel problem
acuTrans -out -to fieldview
creates the file channel_step000005.fv, which contains the nodal coordinates, element connectivity, boundary surfaces "EBC: outflow" and "OSF: wall surface", and the nodal values of velocity and pressure. It also creates the file channel_step000005.fv.fvreg.
When fieldview_options is set to split, FieldView split file format, version 2.7, is used. Here the mesh is written to a file named problem_mesh.fv, while the nodal solution of each time step is written to the file problem_step.fv. A FieldView region file named problem_mesh.fv.fvreg is also created. For example, the channel problem
acuTrans -out -to fieldview -fvopt split
creates the files channel_mesh.fv, channel_step000005.fv, and channel_mesh.fv.fvreg. This option eliminates duplications in mesh output. However, you need FieldView 8.2 or later to read these files.
The FieldView region file contains information that helps FieldView to decompose the information in the .fv files. It is not required in general but it is necessary for parallel visualization. The parameter fieldview_region controls how regions are created. A value of single creates a single region, medium creates one region per medium, fluid, solid, shell, and none, element_set creates one region per element set, and domain creates one region per original subdomain.
acuTrans -out -to fieldview -no_ale
acuTrans -out -to fieldview -ale -deformed_crd_type endstep
acuTrans -out -to fieldview -ale -deformed_crd_type midstep
H3D Format
For H3D format, AcuTrans translates the output data to H3D file format. H3D, or Hyper3D, is a compressed binary file format designed to efficiently store Finite Element model and corresponding result data. H3D files can be visualized by HyperView, a full-featured post-processor, and HyperView Player, a free post-processor viewer.
If the h3d_options option is set to multi, the nodal coordinates, element connectivity, and all surface definitions are written to a file named problem.h3d. The nodal_output results of each time step are written to separate files named problem_step.h3d. For example, the channel problem
acuTrans -out -to h3d
creates the file channel.h3d, which contains the nodal coordinates, element connectivity, and boundary surfaces.In addition, it creates the file channel_0005.h3d, which contains the nodal values of velocity and pressure.
When h3d_options is set to single, H3D single file format is used. Here both model and result data are written in a single file named problem.h3d. For example, the channel problem
acuTrans -out -to h3d -h3dopt single
creates the file channel.h3d, which contains the nodal coordinates, element connectivity, boundary surfaces, and the nodal values of velocity and pressure.
I-deas Format
For I-deas format, AcuTrans translates the output data to the I-deas Universal file format. This is a file format created by Structural Dynamics Research Corporation. The nodal_output results of each time step are written in a file named problem_resstep.unv. The nodal coordinates and element connectivity of the problem are written in a file named problem_mesh.unv, if option mesh_output is set. For example, the channel problem
acuTrans -mesh -out -to ideas
creates the files channel_res5.unv and channel_mesh.unv.
Spectrum Format
For spectrum format, AcuTrans translates the output data to the Spectrum Visualizer compressed ASCII file format. Spectrum Visualizer is a visualization package created by Centric Engineering Systems, Inc., now part of ANSYS, Inc. The nodal_output and surface_output results of each time step are written in a file named problem_resstep.vis.Z. The nodal coordinates, element connectivity, and surface definitions of the problem are written in a file named problem_mesh.vis.Z, if option mesh_output is set. The surface definitions are written as two dimensional elements and their corresponding surface output is written as the projected nodal values of these elements. For example, the channel problem
acuTrans -mesh -out -osf -to spectrum
creates the files channel_res5.vis.Z and channel_mesh.vis.Z.
EnSight Format
For EnSight format, AcuTrans translates the output data to the EnSight file format. This option creates a number of files. The primary one is problem.case, which references the other files. These other files are all contained in the directory ENSIGHT.DIR. The nodal_output results of each time step are written in files named problem.var.step. The nodal coordinates and element connectivity of the problem are written in a file named problem_mesh.geo, if option mesh_output is set. For example, the channel problem
acuTrans -mesh -out -to ensight
FORMAT
type: ensight
GEOMETRY
model: channel_mesh.geo
VARIABLE
vector per node: velocity channel.velocity.******
scalar per node: pressure channel.pressure.******
TIME
time set: 1

Actran Format
acuTrans -oaa -oaas "CAA 2" -to actran -mesh \
-oaav vel,pres,norm_div_total_stress,div_total_stress,div_lighthill_stress
creates the files coordiantes.hdf and res_step.hdf which are HDF5 files to be read by ActranLA from Free Field Technologies S.A. to perform acoustic propagation calculations. The variables listed in this example are the only ones used by ActranLA so they are the only ones translated. All others are ignored.
