I have problem with rotational region. There is no flow or very very small flow between rotational region and rest of the fluid:
I’ve tried to change rotational region
and there is the same story.
I have large tank (aprox. 120x35x4m):
Initial mesh I’ve tried on levels 1,2,3,4 and 5, with 0,001m min gap and 0,003m wall thickness or without manual these manual gaps and there is the same story. Fluid is water, analysis is internal flow. Solver is working fine etc. I’ve tried also different speeds of the rotor – from 300 to 4000 rpm, almost the same story. There is almost no difference if it have local initial mesh area or without it. Anyone know what the problem is?
Thank you in advance,
