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®.
Visualizing Fluid Flow with Streamline Plots
As part of our blog series on postprocessing, we demonstrate the use of streamlines to visually describe fluid flow in your simulations. Learn how with an example of flow through a pipe elbow.
Maximum Evaluations on Parallel Sections
Postprocessing trick: You can evaluate and plot the maximum, minimum, average, or integration value of any variable at various parallel sections along the axial coordinate of your model.
Fillet Away Your Electromagnetic Field Singularities
Did you know that you can use fillets and chamfers in your electromagnetics models to avoid electromagnetic field singularities? Learn how in this tutorial blog post.
Electroplating Simulations for Printed Circuit Board Designers
The manufacture of a printed circuit board (PCB) often involves a process called electroplating, which can vary from design to design. A simulation app can make it easy to analyze this process.
Introducing the Design Module
The Design Module has specialized features for advanced geometry modeling, including the ability to create fillets on 3D designs or generate shell approximations of imported geometric objects.
