Processforge

processforge-logo

A lightweight Python framework for process simulation, coupling hydraulic, thermal, and reactor workflows.

Install

Install the pf command-line tool with uv:

uv tool install processforge

For CoolProp-backed units:

uv tool install "processforge[coolprop]"

Optional solver backends:

uv tool install "processforge[eo]"
uv tool install "processforge[eo-casadi]"
uv tool install "processforge[modelica]"

Quick start

  1. Install the tool

    uv tool install processforge

  2. Download an example flowsheet

    curl -O https://raw.githubusercontent.com/urjanova/processforge/master/flowsheets/hydraulic-chain.json

  3. Initialize, plan, and apply

    pf init flowsheets/hydraulic-chain.json
pf plan flowsheets/hydraulic-chain.json
pf apply flowsheets/hydraulic-chain.json

    plan validates the flowsheet (schema, DOF, units) without running the solver; apply solves it and stores a snapshot.

  4. Look at the output

    pf apply writes results under outputs/:

    • *_results.zarr — simulation results store (per-variable arrays, composition flattened)
    • *_results.zarr.schema.json — schema file describing streams, variables, dtypes, units, shapes, and run provenance
    • *.pfstate/ — versioned snapshot store with a latest pointer

    For flowsheets with Tank units (dynamic), use pf run instead of pf apply to solve with the SM solver.

Python API

from processforge import EOFlowsheet, validate_flowsheet
config = validate_flowsheet("flowsheets/hydraulic-chain.json")
fs = EOFlowsheet(config, backend="scipy")
results = fs.run()

Usage

See the usage guide for CLI commands and workflows.

Individual providers (e.g. FESTIM, OpenMC) can be run via Docker images using the provider image contract.

Flowsheets

The core of Processforge is the flowsheet JSON format, which defines materials, units, and recycle rules. See below for more information on the formats and example flowsheets.
