I am afraid you have to provide some more information. What is that error number and can you get some more output?

T_base = T_ref is a bug. The rest is expected behaviour, see the warning on http://www.coolprop.org/fluid_properties/Incompressibles.html#thermodynamics-of-incompressible-fluids. We might want to fix this by implementing a general solution for the T=T_base...

HI, we are planning on a v6.2 release. Do you think you are able to contribute this fix to it?

The fitting software is right here - the Python classes do all the fitting. See https://github.com/CoolProp/CoolProp/blob/master/dev/incompressible_liquids/CPIncomp/BaseObjects.py#L104

Here is another implementation that uses Modelica: - [Leonard Becker, José Luis Corrales Ciganda 2015 - paper](https://www.researchgate.net/profile/Jose_Corrales_Ciganda/publication/283546795_Fundamental_EoS_Implementation_for_WaterAmmonia_in_Modelica/links/5641bcb108aec448fa61cca4.pdf) - [Leonard Becker, José Luis Corrales Ciganda 2015 - data](https://www.researchgate.net/profile/Jose_Corrales_Ciganda/publication/283634121_20150909_CorralesCiganda_ModelicaConference2015_FundamentalEoSImplementation_for_WaterAmmonia_inModelica_Presentation/links/5641bd3e08ae24cd3e4268b1.pdf)

Maybe the approach from https://github.com/jonathanwww/PiES can help. They use networkx under the hood, but it may give an idea about how equation blocking can be implemented.

You can set the state per fluid, please have a look here: http://www.coolprop.org/coolprop/HighLevelAPI.html#reference-states Do not expect too much from the plotting code, it is partly broken.

Hi - what would be the desired output here? It looks like my changes were not as well prepared as I thought.

I was thinking something along these lines: 1. Single output and only floats as input -> float 2. Single output and one nD array and one float as input ->...

I assume that my last description is what we want - I'll go ahead and start implementing the changes.
