The Advanced EOS Library is a bridge which connects DWSIM on Windows and Linux to a collection of open-source MATLAB/Octave routines which implement various Equations of State, including PC-SAFT with support for associating compounds and the Perturbed-Hard-Sphere-Chain (PHSC).
The original project (http://hpp.uva.es/open-source-software-eos/) consists in a set of MATLAB programs for the calculation of phase equilibrium and other thermodynamic properties using different equations of state (classical cubic equations, cubic equations with excess Gibbs energy mixing rules, group contribution equations and SAFT equations). All programs are open-source and have been designed to be easily reusable using an object-oriented programming methodology.
This library exposes these programs to DWSIM as fully-implemented Property Packages by running them in Octave (https://www.gnu.org/software/octave/) and reading the results through a C# interface (https://www.codeproject.com/Articles/342007/OctaveSharp-Running-GNU-Octave-with-Csharp).
Thanks for downloading this library. You can download it for free (just enter "0" on the amount box) or donate any amount to support the project.
