In a lot of CFD methods it is standard practice to use local time-stepping to obtain steady-state answers much more quickly from a transient solver. I see that SLTS (Stabilised Local Time Step) is a ddt scheme that is available, but I cannot find any meaningful advice on how to use it. The source code asks for "The name of the flux field used to calculate the local time-step" as an option, and when you run the solver, it says that it wants a surfaceScalarField for this. Has anybody here used SLTS?

I've not used SLTS before, but I've had good success using localEuler for the same purpose. There are various tutorials as well -- see e.g. : https://github.com/OpenFOAM/OpenFOAM...AS/SandiaD_LTS.
