Model Builder

The heart of DekEn: a browser-based hydraulic/process network editor. Drag nodes and pipes onto a canvas, set conditions, pick a fluid mode, and solve — GGA, compressible gas, two-phase marching, settling slurry, flare header, and transient MOC all from one canvas.

Unlike desktop tools, the builder runs entirely in the browser against a FastAPI solver. This branch of the manual documents every part of it — from the node palette down to individual valve types — plus how the engine treats each element and where the honesty banners protect you.
