Why don't you just use the mov

Why don't you just use the movingWallVelocity boundary condition - it will update the surface-normal velocity component to correspond o mesh motion. Also, it is much more accurate than doing it by...

The boundary condition is not

The boundary condition is not visible from the solver, i.e. you either did not compile it up properly or it did not link. Put a little print statement in the constructor - when it prints out, you...

- go into the...
