Hey, i have a quite generall question regarding the chtMultiRegionFoam solver.
Considering that the chtMultiRegionSimpleFoam solver only exist in older versions, i have worked with a configuration of the solver that uses steady state for ddt schemes.
However the shell and tube heat exchanger example uses PIMPLE options in fvoptions as well as the steady state ddt schemes.
Does this even match, considering that i always assumed the PIMPLE solver as a solver for transient simulations. Does this mean the simulation is done quasi steady state? Considering that the Courant Number affected the results as well as execution time it might makes sense.

However i spent now enough time searching that i consufed myself and would like to discuss with you guys, so that i hopefully one day end up with a true steady state chtMultiRegionFoam simulation.
