Interpolation for moving/deforming grids? -- CFD Online Discussion Forums

June 30, 2006, 05:11	Interpolation for moving/deforming grids?	#1
Wei Guest Posts: n/a	Hello, I'm trying to run a simulation on moving deforming structured grid. It uses the ALE scheme. deformation is done using arc based TFI. grid velocities are computed explicitly using Peric's space conservation law. so what I need to know is in moving from t=n to n+1, after I've obtained u,v, must I interpolate them to the new grid? Or the u,v obtained are already for the new grid? Thanks in advance.
