NASTRAN SYSTEM(216)=YES

I am using Nastran 2018.2. I see that Patran put this system(216) command into my bdf file. However, when I look in the QRG for 2018, there is no entry for system cell 216. So what does this undocumented feature do?

Toby, I do not see that documented in a current QRG, but I have an old list that shows 216 is related to the iterative solver:

system(216)   keyword=ITER    type=Integer

  Controls execution of iterative solver in SOLs 1, 8, 11, 101, 108, 111  and 106.

  1 or YES: Execute iterative solver.

  0 or NO: Do not execute iterative solver (Default).

This is probably better triggered using the SMETHOD case control command and ITER bulk data entry.
