Is mFem the good tool for mesh smoothing for CFD polyhedral mesh? #4715

Hi @otaolafranc, MFEM can be used to smooth (unstructured) meshes made out of tets, hexes, 3-sided prisms and 4-sided pyramids in 3D. We do not currently support general polyhedra, though there have been some efforts in this direction. In addition to smoothing, you can also use MFEM to build applications in many fields, including CFD, see the Navier miniapp. Hope this helps, cc: @kmittal2, @vladotomov, @rainiscold, @jandrej |

Hello,
I have never done FEM, but I do CFD simulations in OpenFOAM. generally with structured meshes and hybrid meshes (structured dominant+unstructured tet and pyr). in the case of structured meshes, I create them by utilities like blockMesh and salome, right now, my main issue is not the block nor the mesh creation but the smoothing of the final mesh. this brought me to search different possibilities of mesh smoothing in open source realm. but the options are quite scarce, and a collegue pointed me at mFem, which i did not know until then. I would like to ask to more experienced people with this library if the mesh smoothing of mfem would be a correct tool for this. in general for non-polyhedra meshes, i generally try to optimize the scaled jacobian which gives great results.
any inputs on this issue?
thanks in advance!
