The following list outlines the AFLR3 meshing options along with their default value available through the AIM interface. By default, these values will be linked to any parent AIMs with variables of the same name, with the exception of the ...
- Proj_Name = NULL
This corresponds to the output name of the mesh. If left NULL, the mesh is not written to a file.
- Tess_Params = [0.025, 0.001, 15.0]
Body tessellation parameters. Tess_Params[0] and Tess_Params[1] get scaled by the bounding box of the body. (From the EGADS manual) A set of 3 parameters that drive the EDGE discretization and the FACE triangulation. The first is the maximum length of an EDGE segment or triangle side (in physical space). A zero is flag that allows for any length. The second is a curvature-based value that looks locally at the deviation between the centroid of the discrete object and the underlying geometry. Any deviation larger than the input value will cause the tessellation to be enhanced in those regions. The third is the maximum interior dihedral angle (in degrees) between triangle facets (or Edge segment tangents for a WIREBODY tessellation), note that a zero ignores this phase.
- Mesh_Quiet_Flag = False
Suppression of mesh generator (not including errors)
- Mesh_Format = "AFLR3"
Mesh output format. Available format names include: "AFLR3", "SU2", and "VTK"".
- Mesh_ASCII_Flag = True
Output mesh in ASCII format, otherwise write a binary file, if applicable.
- Mesh_Gen_Input_String = NULL
Meshing program command line string (as if called in bash mode). Use this to specify more complicated options/use features of the mesher not currently exposed through other AIM input variables. Note that this is the exact string that will be provided to the volume mesher; no modifications will be made. If left NULL an input string will be created based on default values of the relevant AIM input variables.
- Multiple_Mesh = False
If set to True a volume will be generated for each body. When set to False (default value) only a single volume mesh will be created.
- Mesh_Sizing = NULL
See Mesh Sizing for additional details.
- BL_Initial_Spacing = 0.0
Initial mesh spacing when growing a boundary layer that is applied to all bodies.
Note: Both "BL_Initial_Spacing" and "BL_Thickness" must be non-zero for values to be applied. If "Multiple_Mesh" is False (default value) these values will not be applied to the largest body (if more than 1 body exist in the AIM), as that body is assumed to be a bounding box (e.g. a farfield boundary in a CFD simulation). Boundary spacing and thickness specified through the use of the "Mesh_Sizing" input (see Mesh Sizing for additional details) will take precedence over the values specified for "BL_Initial_Spacing" and "BL_Thickness".
- BL_Thickness = 0.0
Total boundary layer thickness that is applied to all bodies.
Note: see "BL_Initial_Spacing" for additional details
