Now I want to do spatial filtering of the pressure field at this complex surface, how can I do this? since it is a non-flat surface, spectral filtering seems not working, if I use Gaussian filtering, the coefficient matrix needs to be change for every grid point? That seems too complex. Any ideas? Thanks
