Problem applying wedge bc
 

Hi

I am trying to apply wedge bc on the opposite patches of a hexahedral block,
for solving axisymmetric flow. But I am not able to generate mesh using
blockMesh. When I change them to "cyclic bc", it works.

Can wedge bc be applied to opposite patches of hexahedral block, or can it
be applied to only wedge shape block.

Please reply.

Thanks
Anant
