Constraints due to symmetric geometry

Hi everyone,

I am modeling a 3D hollow element made by more components in Hypermesh to conduct NLQS analysis with Optistruct.

My system is symmetric and I want to know if there is the possibility to tell the software that the unmodeled part is the mirror of the modeled part, so that it considers the constraints due to the symmetry. I know the software allows to reflects elements, but I would like to not works with too many nodes.

I attach pictures: 1 is the modeled/discretized part; 2 is the entire system (modeled, unmodeled parts)

 

Thanks

Martina

    While post processing in HyperView we have the option of use symmetry. Refer attached screenshot.

     

    Note: OptiStruct 2019 supports Nonlinear Axisymmetric Analysis(this model is not a axisymmetric part)
