| Step | Action | Time |
|---|---|---|
| 1 | Install License Manager | ~10 min |
| 2 | Install COMSOL Multiphysics | ~20 min |
| 3 | Activate license | ~5 min |
| 4 | Configure solver backend | ~10 min |

Install the floating license server first.
Run the COMSOL installer and point it to the license server.
Confirm the license is active.
Choose direct or iterative based on model size.
Start with auto mesh, then refine manually.
Run the built-in tutorial to validate the setup.
- Install License Manager
- Install COMSOL
- Activate license
- Set solver backend
- Run tutorial model
- Tune mesh
- ✅ Use floating licenses for teams
- ✅ Prefer direct solver for small models
- ✅ Use iterative for large models
- ✅ Sweep parameters in batches
- ✅ Script with MATLAB LiveLink or
mph
- ✅ License server first, app second
- ✅ Direct solver = exact, memory-heavy
- ✅ Iterative solver = scalable
- ✅ Auto mesh is a starting point, not final
- ✅ Parametric sweeps save days of clicking
| Problem | Fix |
|---|---|
| License not found | Check server port and firewall |
| Solver out of memory | Switch to iterative |
| Mesh fails | Simplify geometry first |
| MATLAB LiveLink fails | Check path and version match |
Python mph fails |
Install matching mph version |
| Slow parametric sweep | Reduce saved outputs |
