Get high skewness after setting mesh interface in Fluent

MrZZQi · May 31, 2018, 04:28

hello,

I have a problem:

I used a pair of interfaces to connect 2 parts of mesh, and the quality of mesh is greater than 0.39 in Fluent. Before I set up the interface, everything seems fine. And after the set up, when I run "Check Case", the result becomes "Maximum cell skewness is greater than 0.98". And the case become divergent after a few steps (turbulence ration is greater than 1e5).

Is this error caused by the interface? The mesh interface dialog is shown below.

Thank you in advance!

And I checked the mesh in ICEM, the Equiangle Skewness is greater than 0.35 (perhaps means the skewness is supposed to be less than 0.65 in Fluent?)
