WebANSYS FLUENT 12.0 Theory Guide - 18.5 Density-Based Solver 18.5 Density-Based Solver The density-based solver in ANSYS FLUENT solves the governing equations of continuity, momentum, and (where appropriate) energy and species transport simultaneously as a set, or vector, of equations. WebBy default, ANSYS FLUENT uses a 3-stage Runge-Kutta scheme based on the work by Lynn [ 211] for steady-state flows that use the density-based explicit solver. Implicit Residual Smoothing. The maximum time step can be further increased by increasing the support of the scheme through implicit averaging of the residuals with their neighbors.
