Fluids & Thermodynamics
CoolProp in-process, org mixtures and thermodynamic diagrams
PNeX embeds CoolProp as an in-process library (vendored C++ compiled with the Rust workspace) instead of calling an external service.
In flow nodes
The pnex-coolprop node computes fluid properties inside flows, with PropsSI-style
syntax. Custom org-scoped fluid mixtures are supported: composition in JSON,
used by the node and by the diagrams.
Diagrams
Thermodynamic diagrams (p-h, T-s, psychrometric) with cycle points, for pure fluids and org mixtures, rendered as SVG polylines in the app.
