Bounding omega and k are extreme values during solving
Hello,
Trying to do a simulation of an Ahmed body to get the drag coefficient. Whilst I've managed to get down to a difference of 15% between the real and simulation values, I've noticed during my simulations that bounding k and omega values are through the roof (bigger than 1e100). Is this something to be concerned about even though my simulation reports (near) accurate drag coefficients? |

> accurate drag coefficients? Your two statements looks contradictory each other. Bounding turbulent variables are quite common in OpenFOAM. But thats 1e100 is a bit too large. I remember the mesh quality of Ahmed test case is not very good. If you can make the quality better, I am pretty sure the extremely large value will be seriously decreased. |
