Hi

I am using FLUENT 13.0 to simulate the hovering of an insect. I am using the DEFINE_GRID_MOTION macro in my UDF. All my outer domains are walls. There is no incoming flow. I get this pressure correction divergence error after about 20 iterations which is the length of the first time step in my tests.

Does anyone have a clue what's happening?
