Is there any limitations on using multigrid for 3d test cases or parallel run? , I am having a problem.When I run parallel code using mpirun -n 12 SU2_CFD (configname)
I get displayed only multigrid level 0,1,2 on console even when I choose multigrid as 3 in config file .If anyone faced this problem before or have a solution, please reply . Thanks in advance.

SU2 stops the agglomeration of cells if no sufficient coarsening can be achieved any more. So there is an upper limit on the number of multigrid levels for each mesh which you apparently reached.
