Check case help
hey guys im getting this error for check case..
"maximum cell skewness is greater than 0.98. consider improving the mesh quality before proceeding with your simulation." also in the text window "skewness exceeded 0.98 at 15 cells on thread ID = 3.Skewness exceeded 0.98 at 15 cells on thread ID = 3." can anyone explain: -What it cell skewness is? -if this is causing in major errors in the caculations? -and possible solutoins. thanks! |
your mesh contains cells with poor quality.
http://my.fit.edu/itresources/manual...equiangle_skew Fix this issue by modifiying topology (merge,split, etc...) and/or remeshing |
A simulation with cell skewness greater than 0.98 will run but will give awful results such as acceleration of the flow in the middle of nowhere.
You should thing about remeshing the surface mesh (surface skewness < 0.5 will help you to have a cell skewness < 0.9), or using tools such as auto node move (in Tgrid 3d) Adrien Btw, to have good results the cell skewness should be less than 0.9 at least |
Thanks for the help, im using workbench to generate my mesh. What are there imputs that are variable to limit the skewness?
|
Sorry, can't help you with workbench. I never used it, but you have to make your triangular mesh as equilateral as possible and then the cell skewness will be good too
