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.

Introducing the Composite Materials Module
