WebThe explicit time stepping formulation is available only with the density-based explicit formulation. ANSYS FLUENT also uses multi-stage Runge-Kutta explicit time integration for the density-based solver, as detailed in Sections 18.5.4 and 18.5.5. Incompressible flow. Explicit time stepping cannot be used to compute time-accurate incompressible ... WebJan 21, 2024 · Here we develop explicit local time-stepping (LTS) schemes with second and third order accuracy for the shallow water equations. The system is discretized in space by a C-grid staggering method, namely the TRiSK scheme adopted in MPAS-Ocean, a global ocean model with the capability of resolving multiple resolutions within a single …

WebAug 7, 2024 · Rep Power: 10. That's what I was suspecting as well. However I saw different results. But I found the reason therefore: In StarCCM+ the only temporal discretization is first order BWD for the PISO algorithm. For Unsteady Implicit I used second order.
