Caffa o type grid generation
 

I have using caffa for my undergrade thesis for pat 1 year.I have generated c-type grid,and generated the solution solution.But when i generated the o type grid,the solver diverges every time.In the solver and grid,it was mentioned that it work for the o type,but it didn't.Is there further/special modification needed for the caffac code?I have used same solver input code for the o type as in c-type.but the grid file is generated for o type.help me out please:confused:
