Adjusting fvsoluion and fvschems based on the mesh quality!

tareqkh · October 16, 2017, 16:26

Hi All,

I have been thinking about creating an automated file for both fvsolution as well as fvschemes that corresponds to the mesh quality similar to what the commercial CFD softwares use. I am using the "simpleFoam" solver with different quality of meshes. Some of the grids have non-orthogonality <70 and some have non-orthogonality <45. I have been reading through the forum and some of the problems are relevant to the quality of mesh and adjusting both fvschemes and fvsolution. Is there any why to program the most common fvschemes and fvsolution based on the mesh quality?

I would be more than happy to program it if anyone could provide some guide on where to start.

Look forward to hearing from anyone.

Best,

Hi,

Is this what you are looking for as a start?

simpleFoam - wrong results?
