In the framework of the two-phase fluid simulations of the ste am generators of pressurized water nuclear reactors, we present in this paper a geometric versi on of a pseudo-Full MultiGrid (pseudoFMG) Full Approximation Storage (FAS) preconditioning of b alance equations in the GENEPI code. In our application, the 3D steady state flow is reached by a tra… CONTINUE READING
