Coupled solver fluent

WebNov 29, 2004 · The pressure-based solver traditionally has been used for incompressible and mildly compressible flows. The density-based approach, on the other hand, was originally designed for high-speed compressible flows. Both approaches are now applicable to a broad range of flows (from incompressible to highly compressible), but the origins of … WebThe algebraic multigrid (AMG) solver for Fluent simulations is computationally intensive and in flow-only problems typically the coupled solver spends about 60~70% of run-time solving the linear system using AMG. On the other hand, segregated solver spends only 30~40% of run-time in AMG computation.
