Hello every one,
I read somewhere that according to ANSYS documentation maximum aspect ratio is around 18-20. If the maximum aspect ratio is lower than these values mentioned, does that make a problem? I have an O-grid mesh and my geometry is a simple cylinder where I have two phase flow(a bubble column), when I ask for mesh quality in fluent (since I don't know how to check it in CFX, I check it in fluent but i do my runs and solution in CFX.) it gives these values: Mesh Quality: Minimum Orthogonal Quality = 8.39805e-01 (Orthogonal Quality ranges from 0 to 1, where values close to 0 correspond to low quality.) Maximum Ortho Skew = 1.60195e-01 (Ortho Skew ranges from 0 to 1, where values close to 1 correspond to low quality.) Maximum Aspect Ratio = 9.29158e+00 do you think it is good or I need to do a mesh refinement? Thanks for your answer in advance. |
