Extending the buoyantPimpleFoam solver for LTS support

Functionality to add/problem to solve

Implementing the LTS support for buoyantPimpleFoam. I would like to make some test analysis in the HVAC analysis and check, if I can reach a better convergence rather than using SIMPLE(C). In my former company, I used the pseudo-transient method almost all the time for the HVAC analysis. Would be interesting to test as I do have a test case which seems to be quite instable for steady-state algorithms.

Target audience

Mainly HVAC analysis in terms of convergence optimisation and stability. Some cases seems to behave badly by using the steady-state approach (small convective and larger buoyancy forces).

Proposal

Simply implement LTS support for buoyantPimpleFoam.

What does success look like, and how can we measure that?

I would do some HVAC analysis with buoyantSimpleFoam and buoyantPimpleFoam + LTS and compare the results.
