Hi Alvaro,

You may want to check out the polytrope unit under
"physics/sourceTerms/Polytrope/PolytropeMain".

This is used for example in the simulation
"Simulation/SimulationMain/StirFromFile". I don't think this would work
with the 3 temperature solvers in the code, so you would want to be sure
not to include any of the 3T solvers/units. It should be as easy as adding
a line like

REQUIRES physics/sourceTerms/Polytrope/PolytropeMain
>
 to your Config file.
