OpenFOAM has two solvers (chtMultiRegionFoam and chtMultiRegionSimpleFoam ) for simulation of heat transfer across different materials. When a solver has the keyword simple in it’s name in OpenFOAM, it means it uses SIMPLE algorithm for pressure-velocity decouple, Moreover, it represent it is an steady solver.
