running in parallel _ lift and drag

Mike_star · April 1, 2016, 18:06

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.

yes. controlDict is common to all processors. It won't be a problem.
