Modeling of Phenomena Involving Multiple Timescales

This webinar describes the difficulties inherent in simulating temporally multiscale phenomena, and introduces some creative approaches to solving them.
12 Jan 2016

Situations involving a fast and slow physical phenomenon often arise. Consider vibration-induced fatigue of mechanical structures. Vibration happens at a few cycles per second, whereas fatigue takes place over years. But the phenomena are interlinked — fatigue affects vibration whereas vibration causes fatigue.

Simulating such situations on a computer poses a unique challenge — the time resolution required to accurately simulate the fast phenomenon makes the slow phenomenon untenable to simulate. In the first webinar in this series, we will see exactly why this is such a challenge, and the various ways to overcome it. We will briefly touch upon applications in fatigue modeling, engine modeling and erosion modeling, and show one such situation modeled in COMSOL.

Further webinars in this series will treat individual application areas in detail.
