Convert Data to FV-UNS Format Using AcuTrans

When the appropriate command is executed, AcuTrans reads the data from the AcuSolve output database, then writes the data into FV-UNS format.

AcuSolve writes various types of output to disk during a simulation. The types of output are categorized into nodal output and time series output. Nodal outputs are quantities that are defined on each node, while time series outputs are quantities that represent a single value for each variable at each step. Examples of time series output include TIME_HISTORY_OUTPUT, ELEMENT_OUTPUT, and SURFACE_OUTPUT. Examples of nodal outputs include NODAL_OUTPUT, DERIVED_QUANTITY_OUTPUT and RUNNING_AVERAGE_OUTPUT. When AcuTrans converts data to FV-UNS format, only the nodal outputs are eligible for conversion. Time series data cannot be converted. Additionally, the nodal output variables and time steps that are available for translation to the FV-UNS file are controlled by the physics of the problem as well as the output commands present in the AcuSolve input file.

The simplest AcuTrans command necessary to convert data into FV-UNS format consists of a request to convert the nodal output (-out option) and a specification to convert the data into FV-UNS format (-to fieldview option). For example: acuTrans -out -to fieldview.
