Show stress at each step

Altair Forum User

Does anyone know how to make the stress change with each displacement step in an optistruct simulation? Currently when I have it show me the stress heat map, it doesn't change at each displacement step.

Hi,

 

Include NLOUT in your model file

<?xml version="1.0" encoding="UTF-8"?>

The NLOUT entry can be used in the Subcase Information section to select the incremental result output parameters used for Nonlinear Static Analysis and Nonlinear Transient Analysis

If user wants to maintain the increment size, PARAM>EXPERTNL should be turned off.
