* Operating System: **Linux Ubuntu 20.04** * `python --version`: Python 3.9.5 * [x] The bindings work
I remember that this might be an IF97 issue that has nothing to do with CoolProp directly, see https://github.com/CoolProp/CoolProp/issues/1918. Other implementations of IF97 (e.g. the iapws Python package) struggle with...

Those are the versions I have gotten by following the installation instructions for conda.
Hi @maltefritz, thanks for reporting, do you have a minimal working example for that? I guess something like ``` a -> b b -> c b -> d c ->...
Hi @mdonat, you have to add the `NonConvex` on the input or output flow of the `Converter`, and the attribute `min=1`. ```python heat_pump = solph.components.Converter( "heat pump", inputs={b_electricity: solph.Flow()}, outputs={...
Your code is a incomplete, e.g. `times` is never defined, could you add that? Also, the model might be infeasible, because your heat pump cannot provide 200 units of heat,...
Okay, then it was a misunderstanding. I thought the problem was infeasible... After running it, in my opinion, the issue here is, that the problem seems to have an extremely...
> But if I set min=0.5 it is working. Should have even more possible solutions then... Due to the storage operation cost the optimum is then very easy to find:...
