Default calculating lift and drag coefficients _ running in parallel

Hello everyone,

I am simulating a 2D airfoil and calculating lift and drag coefficients using forcecoeffs in openFoam. To do so I think openfoam needs pressure data at each time step, therefore if I do the simulation in parallel can I still calculate the lift and drag coeffs considering that pressure data is not available and is distributed between the processors?

Thank you.

forceCoeffs is parallelised. If you execute the application that runs this function object using the -parallel switch, it will have all the data required.
