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.

Evaluating a Fire-Resistant Overpack for Nuclear Waste

December 26, 2018

Confinement system overpacks are used to safely store radioactive waste. Sogin uses heat transfer modeling to design safe and reliable overpacks that are resistant to fire.

How to Model Piezoelectric Devices as Both Transmitters and Receivers

December 20, 2018

Certain types of transducers can act as both transmitters and receivers. We demonstrate how to use 2 features for modeling this type of piezoelectric device.

Simulating Nonlinear Sound Propagation in an Acoustic Horn

December 4, 2018

The Westervelt model enables you to perform complex acoustics analyses, such as modeling the propagation of nonlinear acoustic waves generated by an exponential horn.
