BC: myMovingWallVelocity

Reported by Željko Tuković

I have notice something strange in movingWallVelocity. If you look at following bit of the code

    if ( myTimeIndex_ < mesh.time().timeIndex() )
    {
        oldoldFc_ = oldFc_;
        oldFc_ = Fc_;
        Fc_ = pp.faceCentres();
        myTimeIndex_ = mesh.time().timeIndex();
    }

Fc will be calculated only ones in the first outer fsi iteration. So I thint "Fc_ = pp.faceCentres();" should be positioned outside/after if block.

@thijsgillebaart Zeljko found a tiny bug in the movingWallVelocity boundary condition 👍
