Exporting High-Resolution Probe Data During a Parametric Sweep

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 …

Using COMSOL Version 6.1 to Plot Non-Converged Results During Compute Attempts

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 …

Extending the Number of Characters Stored in the Log with COMSOL Version 6.1

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 …

Continuity Pairs for Electrical and Thermal Contact

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.  …

Use of Computational Simulation of Medical Technology – Part 7

Multiphysics Modeling of Cooled RF Ablation In previous blog posts, we have provided extensive discussion on the Use of Computational Simulation of Medical Technology[1].  To provide a specific demonstration, this blog post will focus on describing the implementation of a multiphysics simulation of a cooled RF ablation (C-RFA) device. Traditional vs Cooled RF technology Traditional …
