3 Approaches to Modeling Moving Loads and Constraints in COMSOL®

October 22, 2018

Learn 3 ways to model moving loads and constraints in COMSOL Multiphysics®: using variables, interpolation functions, and paths imported from CAD geometries.

Protecting Aerospace Devices via an Ion-Material Interaction Benchmark

October 22, 2018

In outer space and other harsh radiation environments, high-energy ions and protons pierce materials and affect nearby electronic systems. Known as a single-event effect (SEE), the particle radiation can lead to soft or hard errors in devices. Since just one hard error puts a space mission at risk, aerospace engineers must make sure that all critical electronic devices can withstand an SEE. To gain a better understanding of this phenomenon, they can accurately analyze the ion-material interaction using simulation.
