meshing in gambit
 
Hi

what's the solution ?

split the circle in the middle to generate an O-grid. For the mesh in the central part you could mesh each edge separately.

try to split the edge composing the outer circle (on the left of hte picture) in the middle. Do the same for the inner edge

Hi,

Your every thing seem ok, here are few things that you need to do,

1: For outer semi circle region (extreme left) use double sided successive ratio for both small and large semi circles with appropriate same value for Ratio 1 and Ratio 2

2: For 4 end straight edges (extreme right) use same successive ratio and make sure that all edges have arrows in same direction.

I hope this would solve your problem, so :D
