Local Time Stepping (SLTS, CoEuler, localEuler) -- CFD Online Discussion Forums

Alczem Senior Member Join Date: Dec 2021 Posts: 251 Rep Power: 6	Hey everybody! I have been scouting the forum for information about local time stepping for a buoyant simulation. BuoyantSimpleFoam has a hard time converging (pressure residuals won't go down) while buoyantPimpleFoam seems to converge properly, but I would like to speed up the computation by using LTS. I have been testing SLTS and localEuler but I am not sure how I should configure the PIMPLE entry in fvSolution, and my controlDict (the Courant number, timestep and so on). Has someone used successfully these schemes and could spare some time explaining the setup? Thanks for any help you might give!
