hello Evry body please i want to used vof method and k-omega sst turbulence model fo modeling the flow over steppes please how i can chose explicit numerical method

Do you mean explicit time-stepping? Explicit time-stepping is only available in the density based solver, as far as I know.

i used pressure based solver because the flow is in incompressible i have some difficulty for gate good results

For the pressure based solver, you only have implicit time-stepping in Fluent.

ok please how i can chode this option
