- 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 Size Type
    The Mesh size type for Global Mesh Attributes can be Absolute, Relative, Absolute Expression, Relative Expression, Absolute Anisotropic or Relative Anisotropic.
  - Absolute Mesh Size
    If the Mesh size type is set to Absolute, then the Absolute mesh size value needs to be provided.
  - Relative Mesh Size
    When the Mesh size type is set to Relative, the Relative mesh size must be provided.
  - Absolute Expression
    To specify an Absolute Expression, set the Mesh size type to Absolute Expression. This option allows you to specify a simple text expression to set the size of the mesh on all geometric entities within the model.
  - Relative Expression
    To specify a Relative Expression, set the Mesh size type to Relative Expression. This option allows you to specify a simple text expression to set the relative size of the mesh on all entities within the model.
  - Absolute Anisotropic Mesh Size
    To specify an Absolute anisotropic mesh type, set the Mesh size type to Absolute Anisotropic. This option allows you to enter an absolute size and a tensor that defines the orientation of the anisotropy.
  - Relative Anisotropic Mesh Size
    To specify a Relative anisotropic mesh type, set the Mesh size type to Relative Anisotropic. This option allows you to enter a relative size and a tensor that defines the orientation of the anisotropy.
  - Curvature Refinement Parameters
    Turning On the Curvature refinement parameters gives access to the Curvature angle and Curvature mesh size factor settings.
  - Curvature Angle
    The Curvature angle defines the desired mesh edge length to resolve curved geometric features. This is the value of the included angle.
  - Curvature Mesh Size Factor
    Curvature mesh size factor is used to determine the minimum value of the mesh edge length used to resolve curved features.
  - Mesh Growth Rate
    This option is used to control the rate at which the mesh transitions between regions of different surface and volume size.
  - Maximum Sweep Angle
    This option allows you to set the maximum sweep angle for edge blend meshing on a global basis.
  - Example
    This example focuses on the impact of Global Mesh Attributes on the resulting mesh.
- 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.
- 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.
