Add Local Time Stepping (LTS) to Solver
I have been looking through the code for the local time stepping algorithm and it looks like the setrDeltat.h and setInitialrDeltat.h files could be added to any solver to implement local time stepping versus global time stepping. Is this true or am I missing something?

For example, look at rhoPorousMRFPimpleFoam vs rhoPorousMRFLTSPimpleFoam. The only real difference in these two are those two files. The same is true for reactingParcelFoam and LTSReactingParcelFoam as far as I can tell. Thoughts?

Hi LWhitson,

I was wondering quite the same thing considering the solver twoPhaseEulerFoam which can take days for some cases. Did you get any answer elsewhere ?

the implementation of LTS is really that easy.

but the solution are only accurate for steady state solutions.
