Hi everyone!

I have problems in create a symmetry region in mechanical: i have to study a composite specimen that i have built in acp pre, when i move to mechanical's static strutural it doesn't show me the option of symmetry region but only pre-meshed cycling region. Is there something i can do to overcome this problem? Is it possible that with accademic licence is unavailable to put a symmetry region?

Another question: in mechanical's static structural the composite layers are visible only through the mesh (when i put the mesh the layers are well defined, otherwise they are not visible), can i view the layers outside the mesh visualization?

Thanks for the support!

For solids you could use a zero displacement along the symmetry plane normal (and free other 2) to replicate a symmetry boundary condition. If its a surface body then you also need to fix rotations about the 2 axes which lie in the symmetry plane (and free rotation along axis along plane normal), in addition to adding zero displacement along plane normal.

Nice techniques. Thanks a lot.
