Solver Speed-up for Conjugate Heat Transfer with Radiation

COMSOL Multiphysics® can solve conjugate heat transfer problems that include conduction, convection and radiation. Both Surface-to-Ambiant and Surface-to-Surface radiation formulations are available. Follow this link June 2019 COMSOL Electronics Cooling Webinar for our recent Webinar that includes a step by step demonstration of implementation in COMSOL Multiphysics®. When using Surface-to-Surface radiation, we strongly recommend that the […]

COMSOL Tips & Tricks v5.3: Model Methods Feature

COMSOL Multiphysics / Joshua Thomas

New to version 5.3: Model Method Feature To help save time and make analysis more streamlined it is common for us to set up physics with parameterized inputs. Unfortunately, this approach can also mean repeating commands multiple times that can be time consuming and may introduce mistakes. Now you can reduce the time that

Computational Model for Bolometer Design

Multiphysics Modeling / Joshua Thomas

Computational Model for Bolometer Design Bolometers are used in a number of applications including night vision cameras, astronomy, and particle physics to measure the power of incident electromagnetic radiation. The principle of operation is shown in Figure 1: when a strip of conducting material is exposed to incident electromagnetic radiation, energy is absorbed and

Ideation

SpaceClaim / Joshua Thomas

Ideation – What is that? To Ideate or not to Ideate? That is the question. “Ideate” simply means to form an idea, thought or image of; to form ideas, think. (Dictionary.com) “Ideation” is the process of forming and relating ideas. Ideation means to conceive or generate an idea and implement it. Ideation

COMSOL Tips & Tricks – Text-Based Search Filter (v4.4)

Community, COMSOL Multiphysics / Joshua Thomas

COMSOL Tips & Tricks – Text-Based Search Filter Many of us are running Multiphysics analyses with COMSOL. And, of course, the more physics we are solving for the more variables we have available for post-processing. Maybe you are like me and have gotten lost in the sea of available variables when clicking on the
