Density based solver ansys fluent
WebMar 20, 2024 · For some problems (isothermal flows or constant density flows for example) the coupling between equations is not an issue because you decoupled an already weakly coupled system. For strongly coupled problems, the pressure-based solver can become slower than the density-based solver because you rely on the outer iterations to couple … WebJul 24, 2024 · Modern solvers have this treatment to stabilize the solver and you can use the density-based solvers for low Mach flows now too. Pressure-based solvers also can be used for high Mach number flows (I have used it up to Mach 25). They can be less than optimal compared to density based solvers because the momentum-energy coupling is …
