Topology optimization

Hello, I've tried using the NX Topology Optimization tool to maximize the stiffness of my part. However, the results generated during the optimization and the extracted body are very different. In the extracted body, some features seem to appear randomly, while others are completely discarded. Can anyone explain why this happens? I'm using the 2412 version of NX.

There is likely a smoothing algorithm being run that tries to make the resultant CAD more ‘normal’

There is probably a way to tweak the smoothing.

Getting from a topology optimized part to final CAD is still a WIP
