MAT9ORT for cpenta elements
I'am studying how a components performance is affected by the materials isotropic and orthotropic behaviour. The image attached shows the same 3d solid mesh using hexa and penta elements but with an isotropic material (top) and an orthotropic material (bottom). I'am using mat1 for isotropic and mat9ort for orthotropic.
There is a clear difference in stress for the cpenta elements compared to the chexa. Are cpenta elements fully supported for mat9ort or is this behaviour a result of the cpenta element formulation?

Hi Prakash,
I'am using the PSOLID property card with defaults except CORDM -1.
Altair EmployeeHi,
Can you use PCOMPLS instead?
Hi,
It will be difficult to adapt to a PCOMPLS as the material is not ply based. Orthotropic behaviour is due to the manufacturing process.
Altair EmployeeHi Prakash,

CORDM -1 is the element coordinate system and I think this is why you see such results.
Hi,
I have tried both CORDM -1 and BLANK to compare and there is still a noticeable difference in the CPENTA and CHEXA elements.
Hi @Aidan B
Could you let me know what property are you using for solid elements?
CPENTAs are supported with MAT9ORT.
