How does Comsol solve PDE?
To solve the PDEs, COMSOL Multiphysics uses the proven finite element method (FEM). The software runs the finite element analysis together with adaptive meshing and error control using a variety of numerical solvers.
What is PDE in Comsol?
More specifically, partial differential equations (PDEs) describe such changes in more than one independent variable. For example, a change of a system in time (t) and space (x, y, and z) can be described with a PDE.

Which software is mostly used in equation-based Modelling?
Simulink is used mainly in digital signal processing, and automatic control for model-based designs.
What is a solution to a PDE?
A solution (or a particular solution) to a partial differential equation is a function that solves the equation or, in other words, turns it into an identity when substituted into the equation. A solution is called general if it contains all particular solutions of the equation concerned.
What equations does Comsol use?
Many of our users are well aware of the fact that COMSOL Multiphysics can be used to solve partial differential equations (PDEs) as well as ordinary differential equations (ODEs) and initial value problems.
How can I write expression in Comsol?
From Options>Expressions>Scalar Expressions you can write the following expression (a) in terms of the other variables. Then, Comsol will calculate this variable during solution. After solution is complete, you can see the results of ‘a’ from Postprocessing>Plot Parameters. You should write a in the Expression section.
