Works for single component CO2 - Mixtures seems to be a pain still (DWSIM 7.3.2)

Well it was actually a request :-) unfortunately my C++ programming skills are null

@ibell, is this something which is on the road map? also will you expect some of the iterative methods already implemented for single componet Helmholtz energy formulation that would be...

Density is fine 283.086 kg/m3 ``` D = PropsSI("D","P",P,"T",T,fluid_str) ``` When calling via the low-level interface i get nan for viscosity ``` import CoolProp.CoolProp as CP from CoolProp.CoolProp import PropsSI...

Apparently shared libraries are provided it seems, though I assume it is unmanaged code https://nomad-4-user-guide.readthedocs.io/en/latest/LibraryMode.html#

I could extend this request to include some global derivative free solvers, it seems the Nelder-Mead, Brent, BFGS, IPOPT etc are all local solvers like e.g. LibOptimization (although not active...

Thanks for the advice, it seems many pairs with SO2 is missing. However as I try and add them suddenly known pairs starts complaining. ``` from CoolProp.CoolProp import AbstractState import...

The calculation runs but returns a temperature which is not the dew point at the specified pressure. Far from. Things start to go sideways above 30'something bar.

 

Ok one is with SRK but the same applies with PR. There is apparently a regression in the stability of the PVF/TVF algorithm
