How can I get properties of mixtures e.g
ref: http://www.coolprop.org/fluid_properties/Mixtures.htmlCoolProp_Props("Dmass","T",273+100,"P",101.3*10^3,"Helium[0.5]&Xenon[0.5]"
This can't be done directly in the current version of the plugin. It is not clear how to call the apply_simple_mixing_rule() function from the library, it can't be imported as it is not in the export table.

Hi. Notice that Refprop from NIST can't handle He/Xe mixing either. At least version 9.
On the other hand, maple doesn't seem to implement the procedure that Viacheslav points out either, as can be seen in the online documentation for the latest version.
However, very good values can be obtained using Coolprop in SMath and some basic stoichiometry.

is fantastic!
this no work the first time but after I play with the another examples this work, very well
thank you!

Without "pyfile" (inline multiline script). The script should be without comments.
Space padding is necessary here so that inside the script, when a large string is divided into parts, the line break character itself is not divided ( '\n' -> '\ n' ).

Uni, can you please help me how to add python into SMATH, I have python already in system [WinPython 3.9] How I link it up with Smath?
I have working CoolProp

Jean, can you help me how do integrate python in my Smath? I event tried environmental variables under Win10 but didn't work

You should use a double slash for the full path.
In this case, you need to check whether python is available from the command line. If not, it means that the paths are specified incorrectly.

uni, thanks a lot
Can you tell me what is this block you used after python sub-section [i.e with the square bracket & holding script conetnts]
Additionally Razonar sample here is also very intuitive while calculating mixing values

uni, so it means the text inside the block is not automatically generated. Can you please explain the construct
On second note you were correct, I fixed my environment variable under windows %python% now works

I think I have found some problems while using plugin to get phase properties as discussed here: http://www.coolprop.org/coolprop/HighLevelAPI.html#imposing-the-phase-optional
First when using "P|phase_gas" it doesn't accept units & T,P values have to be directly written in SI equivalent
Second there is a value discrepancy when using "P" & "P|phase_gas" for a fluid that exists only in gas phase at that T,P

It seems that multiple instances of SMath can't use the plugin at the same time.
How to reproduce:
1. Open SMath and access any Coolprop function
2. Open another SMath instance: You get an error message

Phase diagrams with CoolProps. ...
Now can show other thermo properties, and get animations.

I have a small feature request that I may be in the wrong spot to make. Anyway, I love how the CoolProp Wrapper is able to keep track of units and it's way more convenient than Excel or Python. Today I noticed that the wrapper is currently unable to handle units for derivatives. For example, the syntax of CoolProp_Props("d(C)/d(T)|P", "T", 300 K, "P", 1 atm, "Water") results in -0.3248 unitless. By doing a central difference around the same temperature with constant pressure, SMath+CoolProp will respond with -0.3248 J/kg·K². Is there a way that we can get the units into the shorter syntax?
