2 Mesh Adaptation Methods: Enabling More Efficient Computations

January 16, 2019

Why adapt your mesh? For one thing, it helps you solve your computational problems more efficiently. Here, we show you 2 methods for adapting your mesh in COMSOL Multiphysics®.

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.

Keynote Video: Simulating the Drying of Cellular Foods

December 25, 2018

How about them (dried) apples? Empa uses multiscale modeling to analyze the dehydration of soft cellular food products, such as dried fruit, and scale their processes for mass production.

Simulating Multiphase Flow in Porous Media with a Low Permeable Lens

December 13, 2018

Modeling phase transport helps you study the multiphase flow through a porous medium (such as groundwater through soil).

Studying Shock Wave Phenomena with a Shock Tube Application

December 10, 2018

Shock waves used to be a theoretical problem only. Then, shock tubes enabled experimentation, but it was costly and inefficient. Enter numerical modeling applications.

Keynote Video: Designing Improved Heart Pumps with Simulation

December 5, 2018

Abbott Laboratories designed “the most complex machine ever implanted into a human being” — an LVAD for heart failure patients — using multiphysics modeling. The result? Saved lives.
