Integration Point of SHELL element

TiepT_21960

Hi, 

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? 

Thanks, 

Tiep.

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)

Thank you
