Every COMSOL plot you've ever admired for its gorgeous, gradient-smooth color field has been touched up. COMSOL averages your results before it draws them. The smooth field on your screen is not exactly what the solver computed. It's called smoothing. How to work with smoothing and what are the best practices?

When you run a time-dependent coupled simulation, let's say, a Joule-heating problem where both temperature and electric potential evolve over time, exporting two separate animations and watching them separately is clunky. COMSOL gives you at least two clean ways to place multiple plot groups side by side inside a single animation. This article walks through both: the modern Array approach available since COMSOL 5.x, and the classic Deformation-node offset trick that still wo
