Solving System of Differential Equations in COMSOL Multiphysics

In summary, COMSOL Multiphysics is a software package commonly used for modeling and simulating physical systems, particularly by scientists and engineers. It uses a finite element method to solve system of differential equations, which are mathematical equations that describe how a quantity changes over time or space. COMSOL Multiphysics offers a user-friendly interface and a wide range of built-in physics modules, allowing for the coupling of multiple physics phenomena. It is capable of handling both linear and non-linear system of differential equations with its various solvers and algorithms.

I want to solve a system of differential equations in comsol multiphysics.
So far I have not figured out how to enter a 2nd pde in addition to the existing pde.
Is this possible, and how?

Bit old but perhaps someone else will come across something similar ... if you can't implement the PDE by adding variables to the PDE form (physics --> equation systems, it's able to describe fairly general systems), you can always make your problem a "multiphysics one" by adding a new application mode which describes your another problem.
 

1. What is COMSOL Multiphysics?

COMSOL Multiphysics is a software package used for modeling and simulating physical systems. It is commonly used by scientists and engineers to solve complex problems involving multiple physics phenomena.

2. What are differential equations?

Differential equations are mathematical equations that describe how a quantity changes over time or space. In the context of physics and engineering, they are used to model systems with changing variables, such as heat transfer, fluid flow, and electrical circuits.

3. How does COMSOL Multiphysics solve system of differential equations?

COMSOL Multiphysics uses a finite element method to discretize the system of differential equations into a set of algebraic equations. These equations are then solved using numerical methods to find a solution that satisfies the boundary and initial conditions specified by the user.

4. What is the benefit of using COMSOL Multiphysics for solving system of differential equations?

COMSOL Multiphysics offers a user-friendly interface and a wide range of built-in physics modules, making it easier for scientists and engineers to model complex systems. It also allows for the coupling of multiple physics phenomena, which is often necessary in real-world applications.

5. Can COMSOL Multiphysics handle non-linear system of differential equations?

Yes, COMSOL Multiphysics is capable of solving both linear and non-linear system of differential equations. It offers a variety of solvers and algorithms that can handle non-linearities and provide accurate solutions for complex systems.
