AcuConsole Mesh Generation Manual
Instruction of the mesh generation capability in AcuConsole, a GUI based pre-processor for AcuSolve.
- Setting Mesh Attributes
  Mesh attributes control various aspects of the mesh generation process, including mesh size. Mesh attributes can be set on a global (whole model) and/or local (model entity) basis.
- Overview of Meshing Process
  AcuMeshSim is a standalone C++ program. It can be run from the command line, but is more often run directly from AcuConsole.
- Overview of Mesh Controls
  Mesh controls are used to control the size and characteristics of the mesh in different areas of the model.
- Mesh Size
  Mesh size can be roughly equated to the edge length of the elements generated by the mesh generator.
- Curvature Meshing
  Curvature meshing attributes are extremely useful for capturing the curvature in the model during mesh generation.
- Periodic Meshing
  Periodic boundary conditions are used in AcuSolve when only a subset of the full flow domain is simulated.
- Extrusion Meshing
  In certain simulations the flow domain may have a very high aspect ratio. Extruded elements can be used in this case.
- Zone Mesh Attributes
  Mesh size can also be specified as a function of location. Geometric shapes such as spheres, boxes and cylinders can be drawn and mesh sizes are specified for the volume enclosing these Zone Mesh Attributes.
- Global Mesh Attributes
  The Global Mesh Attributes represent mesh settings that are applied to the entire model. Additionally, the size specified in this panel is used as the global mesh length scale that is used in the octree method when evaluating all subsequent mesh sizes.
- Mesh Process Attributes
  All of the mesh features in this section are advanced, and in most cases you do not need to change any of them.
  - Ensure Elements Have Interior Vertices
    Ensure elements have interior vertices modifies the mesh to ensure that it has at least one vertex in the interior.
  - Shrink Mixed Flag
    Shrink mixed flag sets the method that the boundary layer uses to resolve overlapping mixed volumetric elements.
  - Surface Mesh Snap on Match Flag
    Surface mesh snap on match flag turns on/off the "snapping" of destination vertices during the mesh matching. By default it is set to On.
  - Surface Mesh Smoothing Flag
    Surface mesh smoothing flag is set to On by default.
  - Surface Mesh Proximity Size Level
    Surface mesh proximity size level performs isotropic refinement of the surface mesh in areas determined to be thin through the volume.
  - Surface Mesh Face Rotation Angle Limit
    Surface mesh face rotation angle limit sets the face rotation limit angle for meshing discrete models.
  - Surface Mesh Fix Intersections Flag
    Surface mesh fix intersections flag is set to On by default. This sets how the surface mesher checks for and fixes self intersections.
  - Volume Mesh Optimization Flag
    Volume mesh optimization flag turns on/off volume optimization. By default it is set to On.
  - Volume Mesh Smoothing Flag
    Volume mesh smoothing flag by default is set to On. This provides an option (Volume mesh smooth level) for setting the level of volume mesh smoothing.
  - Volume Mesh Enforce Size Flag
    Volume mesh enforce size flag controls interior mesh size enforcement.
  - Surface Mesh Improver Flag
    Surface mesh improver flag is set to Off by default. Turning it On provides additional options for surface mesh improvement.
  - Volume Mesh Improver Flag
    Volume mesh improver flag is set to Off by default. Turning it to On provides additional features for volume mesh improvement.
  - Boundary Layer Minimum Aspect Ratio Flag
    Boundary layer minimum aspect ratio flag sets the length-to-height aspect ratio target value for boundary layer elements.
  - 2D Boundary Layer Minimum Aspect Ratio Flag
    2D Boundary layer minimum aspect ratio flag sets the length-to-height target aspect ratio value.
  - Boundary Layer Exposed Ratio Flag
    Boundary layer exposed ratio flag sets the height-to-length exposed aspect ratio for boundary layer elements.
  - Edge Blends Smoothing Flag
    Edge blends smoothing flag sets additional behavior to grade heights of edge blend boundary layers.
  - Small Feature Meshing Flag
    By enabling the Small feature meshing flag, you can set the type and tolerance for meshing of small features in the model.
- Volume Mesh Attributes
  Every geometric model in AcuConsole contains one or more volume groups. The pipe example model has one volume group called fluid with one geometric region.
- Surface Mesh Attributes
  Once the geometry is imported into AcuConsole, it will have one or more surface groups. Each of the surface groups could have one or more geometric faces associated with it.
- Periodic Mesh Attributes
  To properly set periodic boundary conditions in AcuSolve, the mesh nodes on periodic faces must match after applying the periodic transformation.
- Extrusion Mesh Attributes
  Extrusion meshing is a technique in which structured mesh is created in volume and on surface entities.
- Zone Mesh Attributes
  The Zone Mesh Attributes panel provides a method for you to set mesh sizes in regions that are independent of the CAD model.
- Edge Mesh Attributes
  An edge mesh specifies mesh attributes along a selected edge of a model.
- Mesh Generation Process
  Generating a mesh using AcuConsole requires you to set up the mesh attributes and open the Launch AcuMeshSim dialog.
