Solver
 

Hi, can I run a case using Pressure Based Solver, Cell Based Gradient Option and 1st order schemes for few iterations and then switch to the Density Based Solver, Node Based Gradient Option and 2nd order schemes ? I'm simulating high speed compressible flow, but if I use directly the Density/Node Option either the solution diverge or I have errors.

Thanks

Why can't you just ask Fluent for afew iterations, change the options in the solution panel then continue?
