I am using Optistruct to simulate a implicit nonlinear analysis. I want to use the Simpson's Rule for Integration points through thickness of shell element, so how can i choose Simpson's Rule?
Hi Tiep,
OptiStruct currently only supports Gauss' Rule for integration points through the thickness of shell elements (6 points).
Number of through thickness Gauss points.
If MID2=blank and/or ****=1, the membrane formulation is used. 23
Default = 3 (1 ≤ Integer ≤ 10)
