Comparison
PolySim OS vs COMSOL Multiphysics
COMSOL is beloved for multiphysics, but its per-module pricing balloons quickly and it's a desktop install. PolySim offers browser multiphysics with flat pricing and no module tax.

Where COMSOL Multiphysics is strong
- • Excellent multiphysics coupling
- • Mature model library
- • Strong academic base
Where PolySim wins
- • Per-module cost explosion
- • Desktop install
- • No real-time browser render
