In this webinar, you will see how you can set up and solve your own equations in COMSOL Multiphysics®. The COMSOL® software's equation-based interfaces can be used either on their own or together with the built-in physics interfaces. Mix and match them to let your own custom partial...
One of the core strengths of the COMSOL Multiphysics® software is that you can modify almost any expression in your computational model. This functionality must be used with care, but you can do great things with it. Let’s take a two-dimensional (2D) thermal model with translation, set...

I am trying to solve a set of three "Helmholtz-type" equations using the Equation-Based Modeling of Comsol. There are three independent variables, call them u1, u2, and u3. The equations are (with some constant coefficients in front of each term): ...
The above equations were solved using the equation based techniques in COMSOL .The drift diffusion and the Poisson’s equation governing the physics of the device had been framed to fit into the Coefficient form PDE interface in COMSOL. Appropriate initial values, boundary conditions, mesh size and...
Expression: the expression, using COMSOL syntax, that defines the variable. • Unit: the unit for the variable (in the active unit system). If the unit of the expression does not match the unit of the variable, the expression is displayed in orange. ...
