When modeling a structural component in COMSOL, the type of support you choose—fixed, pinned, roller, or simple contact—can dramatically change your results. Even if you’re only analyzing one part of a larger assembly, its boundary conditions define how it behaves. Fixed supports allow no rotation or movement.Pinned supports permit rotation but restrict translation.Roller supports prevent

In this month’s tips and tricks video, I walk you through mechanical contact without form assembly mode using COMSOL’s new version 6.3. Our team will use this for any scenario where we have a number of bolted connections or any decohesion problems where there’s not a lot of displacement or rotation. The benefit is that

In this month’s tips and tricks video, I share a tip I learned last month at the COMSOL Conference in Boston related to model voids. I will explain what voids are and how you can use them to improve your modeling workflow, particularly with the specific types of geometries I demonstrate. Click below to watch

In this month’s tips and tricks video, I will show you how to use job configurations to combine sequences into a single automated job run, which will enable you to solve for dozens or hundreds of automated layers. Click below to watch as I walk you through the process. To help you follow along, we

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
