[Other] How bad is this mesh?

avinashjagdale · March 4, 2014, 04:21

i have done unstructured mesh on a turbine blade cooling network using Salome.
After converting to polymesh.
I am attaching the checkMesh output.

Can you please give your comments on mesh quality.

It's fine - put a limiter on the laplacian and try 1 non-orthogonal corrector and you are good to go.

Thank you sir. I will put it for solving.
I am also generating mesh on same geometry using snappyhexmesh. Hoping for less non-orthogonality and skewness.
I will post checkmesh log of that too. It will be good exercise to compare both tools.

I am attaching checkMeshlog files for both the cases.
SnappyHexMesh has give much better quality mesh. As you can compare the Non-Orhtogonality Check and Skewness Check for both.

Comments are welcome.
