Alternative to snappyHexMesh for meshing in OpenFOAM with cfMesh - tutorial

[@matt_ttrr]

Very nice video, I had a lot of problems using snappyhexmesh. I am trying to simulate a internal flow, but snappyhexmesh keeps my geometry inside the backgroundmesh. I read that the problem was that I haven't triangulate the surface after modeling the .stl in solidworks. I was trying to use Salome, but I will try to test this too.

The waterproof surface as Tobias Holzmann wrote in CFD online forum.

Yes, that is very important for snappy. Give it a try.

Thanks Jozsef. John

[@markosdavid3926]

It's the best choice.

[@mohammedbabiker9787]

This is interesting , is it supported in OpenFoam-dev ?

[@OpenFOAMJozsefNagy]

I am not sure. But theoretically you should be able to compile it from source.

Hello, This is a very interesting video! I have a question, Did you compare the result of mesh between the cfMesh and SnappyHexMesh? How is the difference for the mesh? Thank you, Aldi

[@OpenFOAMJozsefNagy]

It really depends on the geometry. For the one snappy is better, for others cfMesh.

@kostnermo I am planning it for this year.

all these studies are unnecessary

[@OpenFOAMJozsefNagy]

Others may find it useful

[@kasuora6233]

​@@OpenFOAMJozsefNagy yes it is the important thing but any analysis done in OpenFOAM cannot apply for industry problems. It needs too much develop. For this reason, all these studies are empty. Sorry

@@kasuora6233 Automotive industry, chemical industry, fire safety, medical industry all heavily use OpenFOAM instead of commercial codes. OpenFOAM is among the top 3 used CFD tools in the industry and among the top 5 software overall utilized on HPC clusters world wide.
