Fea Python Packages

pyvista-frd-reader

Read CalculiX FRD result files into PyVista, backed by a C++ core with a C ABI.

pynastran

A Python-based interface tool for Nastran's file formats

felupe

Open finite element infrastructure for nonlinear computational mechanics.

easyfea

EasyFEA is a user-friendly Python library that simplifies finite element analysis.

matadi

Material Definition with Automatic Differentiation

qf-solver

Open-source Python FEM/FEA solver for structural mechanics and dynamics, with transparent formulations, reproducible V&V and PETSc/MPI large-scale solving

abaqus-mcp

MCP server for Abaqus/Standard FEA: builds models, runs jobs headless, and autonomously diagnoses and fixes solver failures

sim-cli-core

Turn existing CAE files into structured text an agent can use — COMSOL, Abaqus, Fluent, HFSS, Icepak, FloTHERM — plus solver detection, script linting, and live solver sessions. Strong coverage for electronics thermal and advanced packaging.

openpile

Pile calculations package. OpenPile aims to be democratize pile calculations for engineers and researchers in academia.

femsections

Finite Element Method (FEM) in Python

sim-plugin-comsol

Use Codex and Claude Code with COMSOL via sim-cli: .mph inspection, live Desktop sessions, bounded execution, artifacts.

hyperelastic

Constitutive hyperelastic material formulations for FElupe.

runabq

runabq is a command tool that can execute multiple input data files of FEA software Abaqus in succession.

febio-python

A python toolkit for pre- and post-processing FEBio Simulations

pyccx

A library for creating and running 3D FEA simulations using the opensource Calculix FEA Package.

femethods

Finite Element Methods (FEmethods) can be used to calculate the shear, moment and deflection diagrams for beams. FEmethods can solve both statically determinant and statically indeterminate beams.

sim-plugin-workbench

Use Codex and Claude Code with Ansys Workbench via sim-cli: journals, project inspection, persistent sessions, Mechanical handoff.

compas-fea2

Finite Element Analysis toolbox for the COMPAS framework.

compas-fea

COMPAS interface to common Finite Element Analysis software.

axfluxmdo

Python toolkit for parametric modeling, simulation, 3D visualization, and multidisciplinary design optimization (MDO) of axial-flux permanent-magnet motors

vcams

Voxel-Based Computer-Aided Modeling Software for Complex Structures

sim-plugin-abaqus

Use Codex and Claude Code with Abaqus via sim-cli: CAE/noGUI authoring, batch jobs, ODB diagnostics, bounded execution.

st7-wrap

Python wrapper around the Strand7 R3 API

sim-runtime

Turn existing CAE files into structured text an agent can use — COMSOL, Abaqus, Fluent, HFSS, Icepak, FloTHERM — plus solver detection, script linting, and live solver sessions. Strong coverage for electronics thermal and advanced packaging.
