Convergence moving mesh

Note that the wall boundary needs to be specified in terms of absolute velocity, so a moving wall with no flux through it will not have fixedValue (0 0 0). If this is the problem use the movingWallVelocity b.c., which corrects the normal component based on the mesh motion.

As a test, have a look at the fluxes through your wall boundaries - if all is well, they should be exactly zero.
