NULL pointer pb

I am using Fluent 6.3 for a patient-specific analyze. I generate my volume mesh under Gridgen. I have 1 inlet and 19 outlets. First, I grouped the outlets so that Fluent was seeing only 2 outlets (left and right group). Then, I set different boundary conditions for the 19 outlets under Gridgen in order to be sure Fluent will separate it. my problem is, now, after trying many times with different changes on the mesh, Fluent is keep telling me "Null Domain Pointer" when I read my cases.
I am stuck there and I still don't understand to to overcome this situation.
Any ideas?

pb solved: it was due to the fact that apparently fluent does not support to many different BC data from Gridgen. I realized that it's possible to separate a region in 2 or more faces under Fluent.
