I am a COMSOL employee, so I do not use other tools. https://www.comsol.com/model/98011 performs topology optimization of heat conduction coupled to laminar flow in 2D. Extension to 3D is conceptually trivial, but in practice one has to use iterative solvers, possibly on a cluster.

Have you ever topology-optimized the heat conduction coupling laminar flow with COMSOL? Or maybe you use other tools?

Thanks so much for your reply, I will take a look at the case and check my settings again.

You probably chose interpolation functions which caused that design to become a (local) optimum. It is possible that you can benefit from taking a look at https://www.comsol.com/model/98011.
