Galilean Invariance
The laws of motion are the same in all inertial frames. (wikipedia)
The moving mesh unconditionally shows satisfactory results of the Galilean Invariance even in the low resolution tests contrat to the static mesh.
Results given in the static mesh with bulk velocity obviously show discrepancy from those without bulk velocity.
