[Faculty] Fwd: [CSRC-SDSU COLLOQUIUM]: Modeling of Phenomena Involving Multiple Timescales

[Jose Castillo]

*DATE*:  Friday, February 26th, 2016

*TITLE*:  Modeling of Phenomena Involving Multiple Timescales

*TIME*:  3:30 PM

*LOCATION*:  GMCS 214

*SPEAKER*:   Udayan Kanade, CEO of Oneirix Labs.

*ABSTRACT*: This lecture describes the difficulties inherent in simulating
temporally multiscale phenomena, and introduces some mathematical
approaches to resolving such difficulties. Situations involving fast and
slow physical phenomenon often arise, for example, 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 difficult or impossible to simulate. In this lecture we
will see various methods of overcoming this challenge. We will briefly
touch upon applications and show some sample simulations using COMSOL.
