Application-Specific: Polar, Far-Field, and Particle Tracing Plots
When postprocessing your electromagnetics models, you can use polar, far-field, and particle tracing plots to effectively display your results. Learn how to use these 3 plot types here.
Using Perfectly Matched Layers and Scattering Boundary Conditions for Wave Electromagnetics Problems
Learn how to use scattering boundary conditions and perfectly matched layers to truncate domains for your wave electromagnetics problem — and which technique is best for your modeling scenario.
Dielectrophoretic Separation
Dielectrophoresis is a phenomenon in which an electric field is used to control the movement of electrically neutral particles. Learn about how to model this effect in both DC and AC fields.
How to Use COMSOL Multiphysics, a Tutorial Video
New to running simulations in COMSOL Multiphysics®? Get a preview of a step-by-step tutorial video that demonstrates how to set up and solve your first model.
Using General Extrusion Operators to Model Rotation
You can use the General Extrusion operators in COMSOL Multiphysics® to simulate rotating objects exposed to loads. A common real-world example of this is rotisserie-style foods.
Introducing Nonlinear Elastic Materials
Examples of nonlinear elastic material models: Ramberg-Osgood, Duncan-Chang, Hardin-Drnevich, Power law, and more. We discuss how to apply nonlinear elastic materials in your analyses.
Geometry Modeling in Simulation Apps
See how to use cumulative selections and geometry parts when creating simulation apps that can be used to model geometries based on parameterized CAD models.
Implementing the Weak Form in COMSOL Multiphysics
In Part 2 of our series on the weak form equations, we demonstrate how to implement and solve these equations numerically using COMSOL Multiphysics®.
