When it comes to modelling and simulating complicated physics-based systems, COMSOL Multiphysics is a software solution that is not only powerful but also comprehensive and easy to use. It may be used in a broad variety of contexts, including the aerospace industry, the automobile industry, biotechnology, the electronics industry, the energy industry, and many more. […]
Looking for Free COMSOL student license? There are a lot of licence options available, and the processes for installing them vary based on which licence type you have. There are no licence types that limit you to a single operating system, however, you can install on Windows, macOS, or Linux. It is possible to open […]
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 […]
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. Interested to Learn Engineering modelling? Check our Courses? Why would you need to compute the solution […]
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 […]
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. Interested to Learn Engineering modelling? […]

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. Interested to Learn Engineering modelling? Check our Courses? Why Run in Batch Mode? If […]
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 […]
COMSOL image to Geometry: This add-in allows you to utilise a picture as the starting point for your analysis with the Image to Curve add-in. A contour plot of an imported picture is used to generate an interpolation curve, which is produced using the add-in. Afterwards, this interpolation curve may be utilised as part of […]
