PBiCG VS smoothsolver

Posted March 31, 2017 at 12:51 by kindle

And this PBiCGStab is implemented also in the OF-4.x and foam-extend (go downstairs from the post). More specifically in OF-4.x it is added (https://github.com/OpenFOAM/OpenFOAM-4.x/commit/1ca4bbf1d288075a76940d58fdf61cbfc49298ee) and in foam-extend it is modified (https://github.com/OpenFOAM/OpenFOAM-dev/commit/c339d3018c98cb67c3455ab09db316c7c0618d5c).
