At first I make 2D planar case restangular geometry - everething OK.
Then I try to caclulate axial 2D geometry with help of simpleFoam (boundary condition is equivalent to planar). I use wedge, empty for axis etc., make with blockMesh geometry. (I can see it in paraFoam - everything is OK with geometry). But when I try to calculate, it don't converge. Some first steps are OK, then oops. I try to change relaxation factors - it is don't help.
In this case I see that program calculate Vz (but in 2D planar - don't).
Must I change some more parameters for axial case?
