Hi all.
I have a strange problem.
I try to simulate flow between two concentric spheres with different rotating velocities in 2D mode. When I use a quarter of concentric circles the answer is good but when I try similar simulation for a half of concentric circles I got floating point exception error.
Anyone have any idea what should I do to get the answer for half of the circles?
I know the answer is identical for any of the quarters and I can mirror the answer in Tecplot but I need to simulate the half for some reasons.
Sry for the long question and thank you in advance.
