pynumgeo

PyPI · Documentation · numgeo · numgeo documentation

Python API for the finite element code numgeo: the object model of a numgeo input deck, reading and writing input files, validation against what the solver accepts, running the solver, and reading its results — headless, on Windows and Linux.

import pynumgeo as ng

deck = ng.read("model.inp")              # numgeo input -> Deck (mesh, materials, steps, ...)
issues = ng.validate(deck)               # what numgeo would reject or read differently
ng.write(deck, "job/model.inp")          # normal-case, deterministic numgeo input
res = ng.run(deck, "job", job="model")   # run numgeo, judge the outcome from its report files
frames = ng.open_results("job", "model").frames()

pip install --pre pynumgeo               # Python 3.11+; runtime dependencies: numpy, pydantic 2
pynumgeo validate model.inp              # every command also has --json
pynumgeo run model.inp --workdir runs/m1
pynumgeo info "*Initial conditions"
pynumgeo --version

The documentation is built with Zensical from docs/ (pip install -e ".[docs]", then zensical serve); docs/llms.txt is a one-page summary for agents.

pynumgeo 2026.2.0.dev3 is a pre-release (hence pip install --pre) built against the numgeo developer source 834564ed (numgeo2026-v2), with *Model change, friction of 60fca8b5; 2026.2.0 will be released together with numgeo2026-v2. Every input file it writes starts with a header that names the pynumgeo version, its author and the numgeo build it was written for.
