What Are Your Go-To Techniques for Speeding Up Large COMSOL Models?

Hi everyone,

I’m currently working with a fairly large COMSOL Multiphysics model involving multiple physics interfaces, and solver time is starting to become a real bottleneck—especially during parametric sweeps and design iterations.

I’ve already experimented with some common optimizations, but I’m curious what has worked best in real-world projects for others here. Specifically, I’d love to hear about practical techniques you rely on when models start getting heavy.

Here are a few areas I’m exploring:

  1. Mesh optimization – selectively refining only high-gradient regions instead of global refinement
  2. Solver configuration – switching between direct and iterative solvers depending on problem size
  3. Physics simplification – temporarily disabling non-critical physics during early iterations
  4. Study sequencing – solving simpler stationary studies before time-dependent or nonlinear ones
  5. Parameter sweep strategies – reducing redundant recalculations or using grouped sweeps

That said, every model behaves differently, so I’m interested in:

  1. Which optimizations gave you the biggest speed gains
  2. What changes surprisingly didn’t help
  3. Any lesser-known settings or workflows that made a noticeable difference

Looking forward to learning from your experiences ?
