Naming groups

Internally thermal solver uses 7 character group names that cannot contain spaces. Most preprocessors allow group names may have more than seven characters and also allow spaces within the name. You can determine the internal group name assigned by the thermal solver using the LONGNAME subroutine. This routine maps between internal (short) and external (long) group names.

There is a direct mapping from CAD permanent groups to thermal solver groups. Use the user-defined external group name and the LONGNAME subroutine to get the thermal solver internal name.

Within Simcenter 3D or NX, groups are defined by element sets and the name of the element set becomes the full thermal solver group name. Again, the subroutine LONGNAME can be used to get the internal name.

The mappings from long name to internal name appear on the NAME2 entries in Card 9 - NAME2 - Group Name Description - Optional of the INPF file. For more information, see the Thermal Solver Reference Manual PDF.
