WebIntroducing the GEKO Turbulence Model in Ansys Fluent. The GEKO (GEneralized K-Omega) turbulence model offers a flexible, robust, general-purpose approach to RANS turbulence modeling.
WebIn unsteady modelling, you have to select a time step for both solvers (dt_E~dt_L). Thus you can track the particle location, velocity, etc at each time step. However, in general, the time step needed for an Eulerian solver is quite bigger than a lagrangian solver and using a small-time step for both solvers would be time-consuming.
