Test for geometric (space) conservation law(GCL)

Hi,

I've a FVM 2D structured NS solver. The grid moves and the GCL has been implemented using Peric's method. (Int. J Numerical Mtds in Fluids, vol 8. 1037). This involves calculating the grid velocities according to GCL.

In the paper, they did a test with zero velocity and pressure when the grid moves. In this case, the new velocity/pressure should still be zero if GCL is satisfied.

I have a C-grid airfoil which rotates, resulting in deformation. Can I use the test above to check if GCL is satisfied for my case?

Thanks
