Local coordinate systems are created using the command 'CONSTRUCT COORDSYS ...', and attached to a part or set using the command 'PROPERTY ATTACH ...'. The interface produces a coordinate system definition for each such system and places a reference to the system on each GRID card.
For example, the following FEMGEN commands:
CONSTRUCT COORDSYS CYLINDRIC CS1 P1 P2 P3 PROPERTY ATTACH L14 CS CS1
Would be mapped to the following NASTRAN cards:
$ $ GRID POINT CARDS ... $ $ ID C-SYS X Y Z LOC-SYS GRID 1 100. 0.0 0.0 1 GRID 2 98.0785 19.509 0.0 1 . . . . . . . . . . . . etc. $ $ LOCAL COORDINATE SYSTEM CARDS ... $ $ CS1 CID RID1 A,B,C... CORD2C 1 0.0 0.0 0.0 0.0 0.0 1. 100. 0.0 0.0 etc.
