My question is related to the mesh quality generated in ICEM CFD.
What is the minimum quality (as shown in ICEM) required for solution?
If mesh is of bad quality, will the solution diverge or it will converge (continuity criteria 10^-5) to a wrong result?
Which quantity (like skewness, aspect ratio etc) is the most important measure of quality?

Hard to tell which is the actual minimum to get a good solution, I think it depends also a lot on the the physics incoporated into your setup.



I usually check the "quality" measure in ICEM to be above 0.1 (which is quite bad already from a visual check) and CFX can still handle it. Sometimes even bit smaller values. Idk about Fluent or some other solver.
