Hi everyone!

I am looking deeper into the twoPhaseEulerFoam source code. In UEqns.H the following line can be found to include the drag force:

U1Eqn += fvm::Sp(dragCoeff, U1);
Is this correct? I would think that instead of the velocity U1, the relative velocity U1-U2 should be used here...

Kind regards,
