I'm simulating a FSAE car and Im using the same settings as in a simulation i did before and there was everthing right. But now im getting this after 11 iterations and after every iteration i have reversed flow, i haven't had this in my earlier simulation.
I don't know what can be wrong here... I'm using the Surface Wrapper, because of many errors and sharp-edged wings Last edited by dennis722; July 25, 2016 at 06:05. |

i thought we talked about this already,
reduce relaxation factors make sure cell quality remediation is on, right click your regions to remove invalid cells reverse flow is not a problem in the beginning that usually clears up, |

i have no invalid cells, put the acceleration method->none and turned on the cell quality remediation. But i have still the problem
