 Poloidal Fourier filter for the regions 1 and 2 Removes high poloidal mode numbers flux-surfaces while retaining small scale poloidal variations close to the divertor plates. This is achieved by applying a window function that removes the near-divertor part from the data.

subroutine fft_parallel_init (grid)
 Initializes the parallelization of the field-aligned FFT filter. Since each flux-surface is filtered separately, the flux-surfaces are distributed among the MPI ranks in the inter-plane communicator (sml_intpl_comm). To achieve approximately even workload, the distribution of flux-surfaces, tries to assign equal numbers of vertices to each rank. More...

 Toroidal-poloidal Fourier filter for the regions 1 and 2 This version of the filter is parallelized to a high degree for optimal performance, and allows for multiple toroidal mode numbers. Removes high poloidal mode numbers from flux-surfaces while retaining small scale poloidal variations close to the divertor plates. This is achieved by applying a window function that removes the near-divertor part from the data. The windowed data is then low-pass filtered and the high-m variations are removed by calculating x_filtered = (1-win)*x - win*x_filtered

Additionally, only one toroidal mode number is kept.
