Thanks btrueblood! I have looked at some of the papers, but all of them are very condensed and they just write that grid velocities need to be obtained from the modified grid and previous grid data, but none of them show how to. Maybe it's very obvious to everybody but it beats me. I will really...
Hi all!
I am doing a 2D unsteady CFD simulation for an oscillating airfoil on a moving grid. I have a structured grid and I know the grid locations at all time instants.
But, I am not able to figure out ""how to calculate the grid velocity for any cell?
Also, how do I use this to "implement...
