Implementation of Member Size Constraint and AM Overhang Constraint in Topology Optimization
how are the Minimum member size constraint and the AM Overhang constraint implemented in the Topology Optimization Tool of ANSYS 19.2?
From the results I get from the Topology Optimizations with ANSYS I would think the mimimum member size is implemented either as a filter or with the Perimeter method.
For the AM Overhang constraint I would guess it´s implemented somehow implicid e.g. with a penalty factor in the objective function, since the overhang constraint is violated for small retained volume percentages.
Can anyone tell me how both are really implemented? That would be very helpful to understand the problems I figured out with the constraints.
