How to Perform Structural Analyses Using Shock Response Spectra

January 30, 2019

Mechanical engineers: Learn how to find shock response spectra, use combination methods for eigenmodes, perform missing mass correction, and display your results with the COMSOL® software.

Improving Fire Protection for Structures via Building Physics Simulation

January 29, 2019

“I didn’t know there was a fire drill scheduled for today,” you say to a colleague. “There isn’t,” they respond. Then you smell smoke. Continue the story in this blog post on building physics.

Keynote Video: EPFL Uses Simulation to Design a Hyperloop Pod

January 22, 2019

The EPFLoop team used multiphysics simulation to design the aeroshell, pressure vessel, and braking system of their hyperloop pod for the SpaceX 2018 competition. Get an inside look here.

Simulating Fluid-Structure Interaction in a Ball Check Valve

January 21, 2019

Simulate FSI in a ball check valve to find the flow rate, fluid pressure, and fluid velocity. The COMSOL® software includes a predefined multiphysics coupling that makes it simple.

Comparing 2 Shock Response Analyses for a Computer Circuit Board

January 18, 2019

Before hitting the market, motherboards and other fragile electronic components need to be able to withstand certain mechanical shock loads. That is where shock response analysis comes in.

How to Model Fundamental Sources in Enclosed Spaces

January 17, 2019

How do Archimedes, a gold crown, and a bathtub relate to acoustics modeling? Find out in this blog post on modeling fundamental sources in enclosed spaces that will have you shouting “eureka!”

How to Model Fluid Friction in Joints with COMSOL Multiphysics®

January 9, 2019

Follow along as we demonstrate how to model fluid friction in joints using 2 rotordynamics examples: a piston and a reciprocating engine.

Maintaining Cold Temperatures in an Isothermal Box with Simulation

December 31, 2018

Heat transfer modeling is more accurate when you can input historical climate data from ASHRAE, such as in this example of an isothermal box designed to transport perishable items and medicine.
