Use Editor Tools to Simplify Your App-Building Process
Get a demonstration of how to create an app using a simple simulation example, as well as how to perform common user interface creation tasks more easily in the Application Builder.
AltaSim Designs and Deploys Apps to Spread Simulation Power
At the COMSOL Conference 2015 Boston, Jeff Crompton from AltaSim Technologies spoke about building, sharing, and deploying simulation apps — and what this means for the future of simulation.
Exploiting Periodicity in Models with High Péclet Numbers
In the study of chemical species transport, a high Péclet number means the ratio of advection to diffusion is very high. Learn how to exploit periodicity when modeling this type of problem.
Why Wolfspeed Builds Apps with COMSOL Multiphysics
Engineers at Wolfspeed used the Application Builder in COMSOL Multiphysics® to optimize their development of wide bandgap semiconductors for silicon chips.
How to Solve for the Brachistochrone Curve Between Points
See how to use built-in mathematical expressions, the Optimization Module, and COMSOL Multiphysics® to solve for the brachistochrone curve.
Part 2: Mapping Variables with General Extrusion Operators
Learn how to use the General Extrusion operators, which are designed to handle nonlinear mappings and the mapping of variables between geometric entities of different dimensions. Part 2 of 2.
Accessing Nonlocal Variables with Linear Extrusion Operators
In some modeling scenarios, you may need to transfer variables from one region of a computational domain (the source) to another (the destination). This can be done with an extrusion operator.
Finding a Structure’s Best Design with Topology Optimization
Think about the first architects who designed a bridge above water. The design process likely included several trials and subsequent failures before they could safely allow people to cross the river. COMSOL Multiphysics and the Optimization Module would have helped make this process much simpler, if they had computers at the time, of course. Before we start to discuss building and optimizing bridges, let’s first identify the best design for a simple beam with the help of topology optimization.
