[QUOTE="Strum, post: 5532970, member: 511314"] Is p_{i,j} the Fourier transform? You should take care that the method does not produce some unwanted complex phase which might ruin the solution. The kx=0 entry is the mean value for that "row" so you can not just set it equal to zero. I would imagine it depends a bit on your RHS how to best proceed. PS: If you want to keep it fully spectral you could solve in the y-direction using a cosine transform. [/QUOTE]
