How to Compute Distances Between Objects in COMSOL Multiphysics®
Compute the distance between two deforming objects in the COMSOL Multiphysics® software. Here’s how…
Generating Animations to Visualize Your Simulation Results
If you’ve read the COMSOL Blog before, you might know that we like to include animations in our blog posts to help illustrate concepts more clearly. Most of these animations are exported directly from the COMSOL Multiphysics® software, which means that you can export animations for your own simulations, too. At the bottom of this post, we link to a video to show you how to do that.
Enhance Your Visualization Plots with 6 New Color Tables
You’ve generated your simulation results and you want to communicate your findings with other people. To do so clearly and effectively, you will need to create easy-to-understand, eye-catching visualizations. Therefore, as of COMSOL Multiphysics® software version 5.2a, you now have six new color tables to further enhance your postprocessing. Let’s learn about the inspiration behind these color tables and take a look at a few specific use cases.
Plotting the Algebraic Residual to Study Model Convergence
You can use the residual operator, new with COMSOL Multiphysics version 5.2, to evaluate and plot your model’s algebraic residual in order to troubleshoot convergence issues. This blog post demonstrates the use of the residual operator for visualizing and understanding the convergence properties of a turbulent flow simulation.
Using Annotation Plots in Your 2D and 3D Plot Groups
Adding annotation plots to your plot groups is an easy way to label the plots of your simulation results with names, comments, and values of quantities evaluated at specified locations. In this blog post, we’ll explore adding annotation plots to a model of a heat sink.
The Power of the Batch Sweep
Have you ever run a large parametric sweep overnight, only to discover the next morning that the parametric solver is still not finished? You may wish you could inspect the solutions for the parameters that are already computed while waiting for the last few parameters to converge. The remedy to this problem is to use a batch sweep, which automatically saves the parametric solutions that were already computed on a file that you can open for visualization and postprocessing purposes.
Analyze Thin Structures Using Up and Down Operators
Modeling complex geometries with thin structures can be very costly in terms of computational effort, particularly as such structures require quite a lot of mesh elements in order to resolve them. COMSOL Multiphysics provides dedicated features for modeling thin structures so that such models can be solved efficiently while maintaining accuracy. To set up and postprocess thin structures, COMSOL Multiphysics also provides specialized operators to help you consider all the relevant parameters required for accurate results.
Postprocessing Local Data Using Component Coupling
Component coupling operators are a useful set of tools included in COMSOL Multiphysics. They can be used to derive numerical values, create new coordinate systems, and link different components in the same model. In this blog post, we will explore yet another possibility: Using General Extrusion, one of the component coupling operators, to extract local solution data and postprocess effectively.
