Do you have any solutions yet? As i am also having this issue

I don't do much flow, but the first place I would look is the mesh quality/refinement for the difficulty of the physics.  Flow is often much more non-linear than thermal and most mechanical, so a good quality mesh refined appropriately for the physics will be compulsory for getting an analysis progressing properly.  If it's transient, then time step selection may be important as well.

If you haven't done some smaller / simpler test/example problems that represent a similar effect, then I suggest having a go with that first, to be confident with procedure.

Cheers,
