I am new on this forum so firstly let me introduce myself. My name is Patryk and I am a student of Mechanical engineering in Bialystok, Poland.
I'm working on my school project which is a flow in jet ski drive, an example of axial water pump. My problem is that I getting an error at about 4500 iteration (~2/4 travels): "Solver abnormally terminated! Please contact the support service", but when I'm solving the same simulation but on scaled model, two or three times smaller, there is no error, solver finishing normally.
I tried to do internal and external flows, low and high quality mesh and problem is always the same, solver terminates on true scale model, but on two or three times smaller it doesn't.
I'm working with a cavitation model turned on and rotating region.
I noticed that a while before error appears, density, velocity and pressure suddenly increase their values and sometimes I'm getting an error "Real gas parameters (pressure and/or temperature) are outside the definitional domain of substance properties T<Tmin".
Anyone could help me ?
