BC for wedge patch
 
Hello

I've got som axisymmetry problem. I generated some meshed wedge about 20deg and put all staff into polyMesh directory. My question is what i should have for wedge patches in 0/T 0/p etc files ?

According to 5.2.2 of OF user guide
http://www.openfoam.com/docs/user/bo...#x24-1370005.2
the wedge is only one cell thick and I think it is supposed to have a small angle (<5).
Maybe your results will improve with this change.

I read somewhere on this forum that 5deg is recommendation but not necessity. As for 1cell thick I'm not sure. Now I'm playing with several cell thikness results are poor but i'm not sure this is becuse of that.
