## Conditional statement in comsol multiphysics

Conditional statement in comsol is very usefull for modelling complicated simulations. The core of the function is if((x>lowerlimit)*(x<=upperlimit),valueiftrue,valueiffalse) the value if false is then a second if the statement of the same form, and so on. The “*” in the formula is equivalent to the AND statement. One way is to use conditional expressions. An […]

## Convergence in COMSOL Multiphysics

What exactly is “Convergence”? Convergence in COMSOL Multiphysics: Convergence is defined as the process of arriving at a solution that is very near to the precise answer within some error tolerance or other convergence condition that was previously set. Why would you need to compute the solution in COMSOL if you already know the precise […]

## COMSOL PDE interface – Equation-based modeling

PDE equation-based simulation in COMSOL Multiphysics (comsol pde interface): An equation with two or more independent variables, an unknown function that depends on those variables, and partial derivatives of the unknown function with respect to the independent variables is known as a partial differential equation (or PDE for short). The largest derivative included determines the […]

## Finite Element Analysis (FEA) in COMSOL Ansys etc

The Finite Element Analysis (FEA) method was first presented to the scientific community by Turner et al. (1956). It is a powerful computational technique that can be used to approximate solutions to a wide variety of “real-world” engineering problems that involve complex domains that are subjected to general boundary conditions. In many areas of engineering, […]

## Run COMSOL Multiphysics Simulations in Batch Mode from the Command Line

Learning to run simulations in Batch mode from the command line is essential if you don’t like waiting for each model to complete solving before you can start a new one. It turns out that this is a rather straightforward procedure. Why Run in Batch Mode? If your models are easy to put up but […]

## Finite Element Method simulation in COMSOL

The finite element method (FEM) is a popular technique for numerically solving differential equations in engineering and mathematics. Finite Element Method simulation in COMSOL is a well-known simulation workflow. The classic domains of structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential are typical issue areas of interest. In two or three spatial […]
