"Skin" results output for solid elements
Hi!
I'm calculating big models containing solid elements and I would like to reduce size of my results file by saving only values for boundary skin. I use this technique in other solver and it works fine.
My question is: it is possible to set some parameter or card to do this in Optistruct?
Thank you in advance

Hi,
You can use extract faces and assign PSHELL card
Really? No need to set something 'special' to shell card?
Altair EmployeeHI,
While defining the PSHELL properties for the skin elements, you should define only the membrane properties and not the Bending and Transverse shear properties. So MID1 should be enough.
The thickness of the skin elements needs to be small. So, a thickness of 0.01 should be fine. Specifically, I am not aware on any thickness ranges for the skin elements.
Altair EmployeeHi @timonq I am using HM v 14.0 SE and here SID is available and not greyed out.

With SAMCEF solver, I use membrane element cover solid elements to capture surface stress. These membrane elements have the same material as solid but with very small thickness (about 1.0E-05 mm).
I think you can do the same with Optistruct, but you need define something within shell card to make them like a membrane.
