Complex geometries on Ansys fluent and Simscale Simscale
It happens more than often that i try to clean up and mesh complex geometries on ansys, for example a certain cad i have in Spaceclaim, it won't subtract from the enclosure even if the geometry is perfectly good and simple. Sometimes everything goes well in Spaceclaim but makes errors and warnings in meshing that requires a lot of time and effort to solve.
Most of the time this geometry is easily prepared and meshed on Simscale and i get acceptable quality mesh and converged solution.
Also Ansys mesh and fluent mesh give more meshings options and tools and save the computation power using polyhexcore mesh in case of fluent mesh, making it a better tool to refine regions of interest, however "sometimes" it takes a lot of effort and time to get mesh working with acceptable quality, that would take less time to get it done in simscale but would need more core hours as the no. of elements will be doubled using tetrahedral mesh in simscale.
Why is that? is Spaceclaim not good enough for preprocessing and geometry clean up?
Is there a better tool for preprocessing CAD
It's like Simscale is more robust in dealing with the model
