Solver settings-GMO-rotating coupled motion-very low reynolds no.
 

Hello everyone.

I have a flow3d simulation with a GMO model rotating with very high viscous environment and coupled motion in low reynolds number. I have tried with all the settings in numerics which fails. It says convective flux exceeded or starting with smaller time step or starting with small omega.

I am new to CFD, can anybody help me what settings/numerics I should use to get simulation done? (like maximum/minimum time step, explicit/implicit, GRES or etc..)

Thanks in advance

Hi i also have a similar experience that Flow-3D have difficulty in solving high viscosity fluid (>2Pa-s) problem. Thus would like to understand how the expert solve this kind of problem here. :)
