I'm running problem using flow simulation Solidworks 2018 Sp2 and Sp3, when i run the turbine with rotating region it does not behave to the i want but when i run without rotating region the behavior of the water is exactly what i want, I never had a problem like this in SW 2014 and 2015.

without rotating region
