Set the Solution Sequence
Autodesk Inventor Nastran jobs that run with Helius PFA require the use of the Nonlinear Static solution sequence. To specify this solution sequence:
Open a Nastran input file (.nas) with a text editor.
At the top of the input file, add the following line:
SOL NLSTATIC
Note: You can also write out the full command or use the solution number, rather than the abbreviated command shown above. Refer to the Nastran Reference Guide for more details.
SOLUTION=NONLINEAR STATIC
SOL=106
