Detailed Description

Only a subset of Nastran entities are recognised: shell elements (CQUAD4 and CTRIA3), volume elements (CTETRA) and nodes (GRID). Point masses (CONM2) are recognised in some special cases but are not stored.

All three variants of line format are supported (free form, short form fixed and long form fixed formats), but there are some limitations:

Free form lines must use commas to separate entries, not spaces.
GRID entries must appear before elements that reference them.
INCLUDE statements are not supported, so all contents must appear in the one file.
The BEGIN BULK statement is optional. All file, executive and case control sections are ignored.
