In OptiStruct, the NLOUT card allows the user to control non-linear analysis output frequency.

Starting in v2020.1, two new options, PARAM1 = TIME and PARAM1 = FREQ, were added:

  • to allow the user to request output at specified time intervals
  • to allow the user to skip output at some time intervals (to limit results file size)

The NLOUT, SVNONCNV=YES option can be used to produce partial results for unconverged loadsteps, to aid in debugging.

The NLMON card can be used to produce displacement results for converged and unconverged increments or iterations, to aid further in debugging.
