solver selection_dynamic mesh_leak simulation

Hallo Foamers,

I am trying to do leak simulation, propane gas is leaking from a inlet and in the domain, i have air completely. propane leak stops after sometime, leaked propane because of density, comes down and forms a cloud on the ground.
So, as of now i am using rhoReactingBuoyantFoam, with reactions off. I selected this solver for buoyancy treatment. Is there any other solver which can be used for this case?. I ran the case with this solver, and everything seems good. But, i want to add dynamic mesh (ABR to scalar propane), but this solver does not support dynamic mesh. i had a look at some posts, but didnt found any information on adding dynamic mesh capability to the solver code.

1. which solver is suitable for this application?
2. How to add dynamic mesh capability to a solver?

Any suggestions?

cheers,
nikhil.

In reactingFOAM dynamicMesh.H available in OpenFOAM 8, serves as a reference for reactingbuoyant solver to edit.

cheers,
