What is mufem?

mufem is a highly scalable finite-element framework for multi-physics simulation, driven entirely from a native Python interface. It lets engineers and researchers set up, run, and automate three-dimensional electromagnetic, photonic, and plasma simulations, and their coupled multi-physics problems.

Native Python API to define, run, and automate simulations
Higher-order accuracy on unstructured meshes with curved geometry
Adaptive mesh refinement where it matters
Runs on CPUs and GPUs (GPU on paid tiers)
Fully scriptable — built for AI-driven and agentic simulation workflows
An extensive library of validated example cases
Scales from a single workstation to compute clusters (clusters on paid tiers)

What mufem simulates

Electromagnetics

Electrostatics, magnetostatics, and time-domain and time-harmonic magnetic analysis for electric motors, generators, transformers, and induction-heating systems — including eddy-current and core losses with nonlinear materials.

Photonics & high-frequency

Time-harmonic Maxwell simulation of RF and microwave components, antennas, waveguides, and cavity resonators, with modal and full-wave analysis.

Thermal & multi-physics

Steady and transient heat conduction with convection, coupled with electromagnetic losses for realistic multi-physics analysis.

What every tier includes

Commercial use on every tier — including the free Community tier.
One-line install — pip install mufem from PyPI; your license key unlocks paid-tier features instantly after payment.
Direct support — email support on Individual and Enterprise; community support via GitHub Issues on the free tier.
Docs & ready-to-run examples — full online documentation and a library of validated example cases.
Your work stays yours — every mesh, model, and result you produce is yours to keep and use.

System requirements: Python 3.12 or newer; tested on Linux. Distributed as a Python package via PyPI.

Licensing FAQ

Is the free Community tier really usable commercially?

Yes. mufem installed from PyPI is free to use for both academic and commercial work, with most physics models and parallel runs on a single workstation. Paid tiers add scaling across clusters and GPUs for larger models and faster turnaround, plus specialized models and support. They add capabilities, not permission to use the software.

What happens when my Individual subscription lapses?

mufem falls back to Community-tier behavior. Existing simulations and results remain yours; you keep full academic and commercial use on a single workstation, without cluster and GPU scaling or specialized models.

Do I need a separate license per machine?

No. One Individual license is tied to you as a single user and can be activated on up to 3 machines you personally use (for example a laptop, a workstation, and a cluster account). To free up a seat, contact us at mufem@raiden-numerics.com.

Do I own the results I produce with mufem?

Yes. You retain full ownership of all meshes, simulations, and outputs you generate, under any tier.
