How to give out U in ratio to inflow-velocity
Dear community,
is there a chance to give out the velocity of each field in ratio to the inflow velocity (standardize) it and make it visible in paraView? Maybe with foamCalc? But i have no idea about the syntax? Could someone help me? thank you very much Martin |
You can choose U at your inlet to be 1, and scale your viscosity accordingly? When you normalize your Navier-Stokes equations, it should be not too difficult.

Thank you very much for you answer.
I do not really understand what you mean. It is a post-process work. So i wont make in inflow of 1. Or do you mean, it is possible to scale this in paraView? If you mean this, could you tell me how to do it? |
Well, it depends on what you want to achieven. Of course it can be done in Paraview as well (Calculator of Python Calculator filter). You can also try to solve the non-dimensional Navier-Stokes equations in OpenFOAM, that is equivalent.

Dear Bernhard,
that was helpful, thank you. I used foamCalc to get magU (a scalar) and having this i was able to take the calculator filter to calculate magU/inflow velocity!!! Thank you very much Martin |
