GNNPCSAFT CAPE-OPEN

GNNPCSAFT CAPE-OPEN is a Property Package CAPE-OPEN implementation of our project that focuses on using Graph Neural Networks (GNN) to estimate the pure-component parameters of the Equation of State PC-SAFT. We developed this app so the scientific community can access the model's results easily.

FeOs is used for PC-SAFT thermodynamic calculations such as VLE. Comtypes is used to implement the CAPE-OPEN COM interfaces. Only Windows is supported for now.

How to Use

Installation

You need Python installed.

Installing the GNNPCSAFT CAPE-OPEN Property Package Server

pip install GNNPCSAFTPropertyPackage

Registering the Server

GNNPCSAFTPropertyPackage.exe -regserver

After registering the server, you can use it in any CAPE-OPEN compliant software.

Unregistering the Server

GNNPCSAFTPropertyPackage.exe -unregserver

Running the tests

The Python tests run with pytest. When COCO is installed, the supplied flowsheets are also solved headlessly through COFEStand:

.\.venv\Scripts\python.exe -m pytest -q

If COCO is installed in a non-default location, set COFE_STAND to the full path of COFEStand.exe. The thermodynamic calculations currently use residual properties only; ideal-gas contributions are not part of the current test scope.
