The following list outlines the Astros inputs along with their default value available through the AIM interface. Unless noted these values will be not be linked to any parent AIMs with variables of the same name.
- Proj_Name = "astros_CAPS"
This corresponds to the project name used for file naming.
- Tess_Params = [0.025, 0.001, 15.0]
Body tessellation parameters used when creating a boundary element model. 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.
- Edge_Point_Min = 4
Minimum number of points along an edge to use when creating a boundary element model.
- Edge_Point_Max = 10
Maximum number of points along an edge to use when creating a boundary element model.
- Quad_Mesh = False
Create a quadratic mesh on four edge faces when creating the boundary element model.
