convergence about 3-D flow field!
 
When I compute 3-D flow field with compressor cascade, I find it is very difficult to converge and the residuals vary intricately. The grid is unstructured. I doní»t know the true reason. Please help!! Thank you!

Raintung,using unstructured mesh will decrease the number of mesh.less mesh,faster convergence.And you can set the underrelaxe factor to less.

Thank you!I will try to do that.
