Add periodic boundary condition on a RVE in multi objective topology optimization
Hello everyone,
I am doing a multi objective topology optimization whose design space is a 1*1*1 RVE cube, and I use *dequation panel to define weighted objective function (linear weighting) for the multi objectives.
When making FE calculation, I use *equations to define the multi points constraint (MPC) on all the boundary nodes so as to define the periodic boundary condition and successfully calculated it. But in multi objective topology optimization, when I use MPC, it throws error and seems MPC is not supported in topology optimization.
I want to ensure the periodicity for the optimized structure and make a 3*3*3 model with 3D printing in my next step. So my question is, how could I define the periodic boundary condition for a shear loading case in a multi objective topology optimization?
