The shear profile from lb plane couette flow is wrong, if the mpi node grid is not 1 in the shear_normal directoin. This case is currently not checked for.
Most likely cause is that the Lees Edwards interpolation kernels are always run on the upper and lower ghost layers in LBWalberlaImpl. However they should be only run on ghost layers which actualy represent a domain boundary.
