DAFoam : Topology optimization tutorial pitzDaily

TonioCFD · May 22, 2024, 06:52

Hello everyone !

I am starting a project on aerodynamic optimization and I wanted to ask in this forum if anyone had successfully tested the topology optimization tutorial from DAFoam on the pitzDaily. Indeed, I would like to create a mesh from the displayed alphaPorosity to optimize the flow according to the pressure loss. The goal is to generate an STL file that would take account of this porosity. Do you know if there is any python script file that would help ? I obtained my results by using the IPOPT solver instead of SNOPT which requires a licence.

Hi Antoine, have you compared the solution with IPOPT with that of SNOPT?
