Overview

Create single sequential subcases based on one NLSTAT subcase, and split the load and combine them with CNTNLSUB. This is useful when e.g. load-displacement curves are needed and currently NLSTAT is not writing incremental results into *h3d.

Multiple subcases can be selected. Now also works with LOAD cards (scale factor will be adapted) and enforced displacements (SPCD/SPC will be scaled).

Usage/Installation Instructions

  1. Load NLSTAT model
  2. Run script
  3. Select subcases and define number of increments
  4. Create curves in HV use derived loadsteps

 

Limitation: # only uses LOAD ids in subcaes (FORCE, MOMENT, PLOAD, LOAD, SPCD) - e.g. TEMP is not considered # script is using directories, was not checked with Linux/Mac # only >= HM13.0

Functionality: Quasi-Static Non-linear 

Subfunctionality: Bulk Data Input Results

Interface: Bulk Data Format OptiStruct
