How to Unify the Color Scale in a COMSOL Plot Group
When you plot two results in COMSOL, the colors often do not match. Each plot picks its own color range by default. This makes it hard to compare two plots side by side. Luckily, COMSOL has a simple fix for this. In this article, you will learn how to lock the color scale. This way, both plots use the same colors for the same values. Why the Colors Do Not Match By default, COMSOL sets the color range automatically for each color plot. It looks at your data and picks a minimum

How to Calculate Any Integral in COMSOL Multiphysics
How to calculate an integral in COMSOL Multiphysics with some step-by-step examples. An integral is very often needed when you need to compute some user-defined postprocessing variables, e.g., lift, drag, heat flux, or any other.

Stop Guessing: How to Turn Off Interpolation in COMSOL Plots
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?

Side-by-Side Animations in COMSOL: Visualize Multiple Plots in One Window
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
