COMSOL vs ANSYS (external flow)
good night

I went to one of the COMSOL workshops and saw that the multiphysics capabilities of the software impressive but, when the romance of the presentation finished, I concentrated in doing what I'm familiar with in the trial version they gave to us.
I'm not one expert in CFD or FSI but I found it difficult to do one simple 3D simulation of a (selig 1223) wing. The turbulence models of comsol are very small in number and the solver worked like a tired horse.

Am I doing something wrong or ANSYS CFX is really a better software for external flow ?

Someone that worked with COMSOL and CFX or even FLUENT can tell the differences on results accuracy and configuration possibilities for this type of simulation ???

Why don't you compare the results and performance against one of the open source CFD codes? (There are quite a few of these: openfoam, gerris, openfvm, dolfyn, etc. )

Good luck.
