WebDensity-based Solvers • Density-based solvers traditionally used for compressible flows – Not accurate for low Mach numbers – Fluent uses a transformation to allow density based solvers for low Mach number flows • Density-based solvers can be implicit or explicit – Implicit allows longer time steps while preserving stability at higher ... WebNote, however, that when the pressure-based solver is used, ANSYS Fluent does not automatically activate the viscous dissipation if you have defined a compressible flow model. When the density-based solver is used, the viscous dissipation terms are always included when the energy equation is solved. 5.2.1.6. Inclusion of the Species Diffusion Term
