Topology Optimization of Natural Frequency
I'm running a simulation of a small part, I did a modal analysis to get the natural frequencies of the piece, very simple and it gave a correct output, but when trying to do a topological optimization to reduce material while keeping the natural frequency high, the solver gives me the next error:
'Number of natural frequency exceeds number of calculated frequencies'
It's true that it didn't detect any frequency in the first mode (0), but I've changed the objective to optimize the second mode and still, this error pops out. Any reason why it's not working?
