AIM Inputs

The following list outlines the AFLR3 meshing options along with their default value available through the AIM interface.

• Proj_Name = "aflr3_CAPS"
  Output name prefix for meshes to be written in formats specified by Mesh_Format. These meshes are not linked to any analysis, but may be useful exploring meshing parameters.

• Mesh_Format = NULL
  Optional list of string mesh formats to generate meshes not linked to analysis.
  Available format names include: "exodus", "fast", "wavefront", "libMeshb", "stl", "bstl", "su2", "tecplot", "ugrid", "vtk", and "bvtk".
  where the "b" prefix indicates binary version.

• Mesh_Quiet_Flag = False
  Suppression of mesh generator (not including errors)
• 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 = "SingleDomain"
  If "SingleDomain": Generate a single volume mesh file is assuming multiple bodies define a single computational domain (i.e. CFD)
  
  If "MultiFile": Generate a volume mesh file for each body.
  
  If "MultiDomain": Generate a single mesh file containing multiple volume meshes for each body.
  
• 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 (scaled by capsMeshLength).
  
  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 (scaled by capsMeshLength).
  This is a lower bound on the desired thickness. The height can be limited with "nbl".
  
  Note: see "BL_Initial_Spacing" and "BL_Max_Layers" for additional details
• BL_Max_Layers = 10000
  Maximum BL grid layers to generate.
• BL_Max_Layer_Diff = 0
  Maximum difference in BL levels.
  If BL_Max_Layer_Diff > 0 then the maximum difference between the number of BL levels for
  the BL nodes on a given BL boundary surface face is limited to BL_Max_Layer_Diff.
  Any active BL node that would allow the number of levels to be greater is
  terminated.
  If BL_Max_Layer_Diff = 0 then the difference in BL levels is ignored.
• Surface_Mesh = NULL
  A Surface_Mesh link.
