WebNov 6, 2024 · Hi, I am writing my own functionObject and since I am quite new to OpenFOAM i started off by making a copy of the standard functionObject forces and I am now about to adopt it to my needs. I have managed to understand quite a bit of what is going on in there but on thing that I still don't understand is the binData, that is referred on … WebDescription. The valueAverage function object computes the ensemble- or time-based singular-value average values, with optional windowing, from the output of function objects that generate non-field type values (e.g. Cd of forceCoeffs or momentum_x in momentum function objects). powershell rekursion

For a incompresible case, pressure is really pressure/density. So the forces library multiplies by the density you provide. 3) The forces coefficient that you are calculating seems right, so you will have to redo your simulations, maybe improving your mesh.
