Acceptable Mesh

      How will you know if you have an acceptable or a good mesh? Sorry, I am just a beginner and I want to really explore ANSYS. Thanks!

      So the answer depends on the type of solver you are working with. The following links will provide you all the information about the mesh requirements for the Ansys Fluent and Ansys CFX:


      Ansys Fluent Mesh Quality (Orthagonal quality, Aspect ratio and Skewness)


      Ansys CFX Mesh Quality (Orthagonality angle, Mesh expansion ratio and Aspect ratio)


      Meshing Workshop (Pg 93 - 103)

      Thank you! I observed that when I increase or refine the mesh to have more number of elements, the orthogonality becomes less (lose to zero). Compared to less elements with 0.7 orthogonal value. Any thoughts? Thanks!

      Could you share a schematic of your geometry and mesh or attach your workbench archive here? It would be easier to provide some feedback if we get to see the geometry .
