The following list outlines the EGADS Tessellation meshing options along with their default value available through the AIM interface.
- 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_Format = "AFLR3"
Mesh output format. Available format names include: "AFLR3", "VTK", "TECPLOT", "STL" (quadrilaterals will be split into triangles), "Airfoil", "FAST", "Nastran".
- "Airfoil" corresponds to the following file format in which the nodal coordinates of the body's edges are written. Bodies should be face bodies, planar, and have no holes. A *.af suffix is used for the file:
"Character Name"
x[0] y[0] x y coordinates
x[1] y[1]
... ...
- Mesh_ASCII_Flag = True
Output mesh in ASCII format, otherwise write a binary file if applicable.
- Edge_Point_Min = 2
Minimum number of points along an edge to use when creating a surface mesh.
- Edge_Point_Max = NULL
Maximum number of points along an edge to use when creating a surface mesh.
- Mesh_Sizing = NULL
See Mesh Sizing for additional details.
