The oSP3D Nastran simulate interface can modify valid Nastran input files that:
Meet the requirements given in Importing Nastran Mesh Input Files
Are compatible with the project-related reference mesh
Typically, the simulate feature expects to modify one of the oSP3D project-related valid Nastran mesh input files. The following list, not exhaustive, includes some limitations:
Only the following fields of the
GRIDbulk data entry can be modified:x coordinate in the basic coordinate system
y coordinate in the basic coordinate system
z coordinate in the basic coordinate system
CSV-formatted input files cannot be simulated only. The free-field format is automatically translated into the short or long format respectively. Bulk data formatted in CSV is rewritten. Continuation markers are automatically generated if necessary.
Real data types can miss the decimal point, although the decimal point is required by the MSC.Nastran format specification,
