Is migrating from COMSOL Multiphysics hard?

No — most models map cleanly, and PolySim's AI Copilot can rebuild much of the setup from a description. Our Migration Service can also do it for you.

Will my results match COMSOL Multiphysics?

PolySim uses established numerical methods; validate against a known COMSOL Multiphysics benchmark to confirm equivalence before relying on results.

Migration in five steps

1
Export your model definition
Gather the geometry, materials, boundary conditions, and solver settings from your COMSOL Multiphysics project.
2
Recreate the domain in PolySim
Use the visual node graph, or let the AI Copilot rebuild the setup from a plain-English description or pasted parameters.
3
Map materials & boundary conditions
Assign properties from the PolySim materials database and set equivalent boundary conditions.
4
Validate against a known case
Run a benchmark you already trust from COMSOL Multiphysics and compare results side by side.
5
Scale and share
Run locally for free, scale to the cloud for large jobs, and publish an interactive, citable version.
