Modeling copolymer systems using PC-SAFT eos about feos

[g-bauer]

Hi Jackxi1024,

for your Python implementation you can use the equations for the Helmholtz energy contributions given in the appendix of [1] and our Python package for dual numbers [2] to circumvent implementing analytical derivatives.
Otherwise, the partial derivatives can be carried out for the equations of the Helmholtz energy contributions as described for copolymers just like it was shown in the first PC-SAFT paper you mentioned.

I'm closing this issue since your question is not directly related to FeOs.
