Licensing FAQ
What counts as commercial use?
Any use that produces results, designs, or analyses for a paying client, an employer, or a commercial product. Publishing academic results or sharing open-source examples does not.
Can I evaluate μfem inside a company before purchasing?
Yes. Evaluation in a commercial environment is permitted under the Community tier for up to 30 days.
What happens when my Individual subscription lapses?
μfem falls back to Community-tier behaviour. Existing simulations and results remain yours; only commercial use stops being permitted.
Do I need a separate licence per machine?
No. The Individual tier is tied to a single user, not a single machine.
Do I own the results I produce with μfem?
Yes. You retain full ownership of all meshes, simulations, and outputs you generate, under any tier.
