Most efficient implementation of the pressure poisson solver

Divyaprakash · November 18, 2022, 00:36

I have written a simple CFD solver following the steps here https://www.montana.edu/mowkes/resea...GuideToCFD.pdf
I have implemented this in Fortran.

I want to know what options do I have to solve the pressure poisson equation as efficiently as possible?

I am looking for suggestions on the best algorithm to use and the best libraries in C/C++ or Fortran which will give me the maximum computational efficiency. Thank you!

For Cartesian mesh solvers as yours - it will be FFT based or Cyclic reduction based solvers (Check fishpack library).
