I'm working on doing parameter studies with EnergyPlus and changing HAMT definitions. Which means I want to sweep through different adsorption isotherms etc. As it seems not possible to change them on the fly by the ExternalInterface Functionality, I plan to generate many different IDF files. Has anyone done similar simulations? I would like to exchange experience about that. And by the way: has anyone experienced an unusual difference in the thermal mass (heat storage) when switching from CTF e.g. to the HAMT solution algorithm?
