Tetramesh and Lamniate
Altair EmployeeHi
I have a complex geometry, with some parts made of 'solidcarbon' where i can only use a tetramesh or solid mesh (no solid layer). How can i define the laminate for this tetramesh parts? I have only to create an equivalent orthotropic material with hyperlaminate and use a MAT9? Or Is it possible define the laminate and to have a poor evaluation of the stress in each ply?
Regards

You can use MAT9 or MAT9ORT for solid elements, but prefer hexa elements instead of tetra.

Unfortunately I can use only tetra elements. But it's not really clear for me or to define the laminate in MAT9

Unfortunately it is not possible to create a literal laminate in OptiStruct with solid elements.

What type of approach do you suggest?

One approach is to have nodal connectivity between layers.
