Ever find yourself in a situation where you want to combine multiple datasets to create a single dataset for seamless animations and other post-processing operations? In this month’s tips and tricks video, I share a scenario that allows you to combine two separate transient studies without having to use separate editing software for video preparation. […]

COMSOL has made some solver improvements to Version 6.2 of repeatability in chaotic simulations, which has been helpful for a particular project we’re working on for a customer. In this month’s tips and tricks video, we share an example of how this solver improvement helps us get the same answer with the same initial input

Through experience, we discovered that if you want to develop an accumulated probe table, it doesn’t export the full resolution that you requested under “Updating probes.” So, in our latest Tips & Tricks video, I walk you through three steps you can take to export high-resolution probe data during a parametric sweep. Click below to

Fly-through animations are a creative way to visualize inside 3-dimensional plots. In our latest Tips & Tricks video, I demonstrate how to develop these fly-through animations. The trick is, once you have your results stored in your data set, you need to define a results parameter that will be used to govern a filter of

As an engineer have you ever found yourself in a situation where you’re trying to track non-converged results by plotting solution variables that you would expect to behave in a certain way, but you’re not sure how to modify the initial values? In our latest Tips & Tricks video, I take you through a scenario

In some cases, the information in the log file of a simulation is lost when the maximum number of characters in the log file is exceeded. In this video tip, we show how to increase the maximum number of characters to provide access to important data. To help you follow along, we have included the

We are excited about the new release of COMSOL Version 6.1 and wanted to share a new feature with you, so we put together this quick video. To help you follow along, we have included the video transcription below.   If you’re new to COMSOL, we invite you to register for our introductory class, Multiphysics

Thermal stresses are an important design concern for many engineering applications.  When temperatures change, materials can deform or warp leading to the build-up of internal stresses even without the presence of external constraints which can further increase thermal stresses.  Modeling and simulation can calculate the deformations, stresses and changing contact pressures using thermal-structural interaction techniques. 

Many engineers solve heat transfer challenges regularly. Over the last 20 years, AltaSim has developed hundreds of simulations for our clients that include heat transfer as a component. This Tip comes from our experience in solving a heat transfer problem that included thin layers of different materials. Solid elements are the most widely used type
