Tune into this webinar to get an 18-minute introduction to modeling ray tracing in the COMSOL Multiphysics® software.

Ray tracing can be used to model electromagnetic wave propagation in systems in which the wavelength is much smaller than the smallest geometric detail in the model. Stresses, temperature changes, and other physical phenomena can often affect ray trajectories, either by deforming the geometry of the domain or affecting the refractive indices within the domains. Modeling such multiphysics applications is possible in the COMSOL® software.

High-powered rays can generate significant heat sources that affect the temperature field and may cause notable thermal stresses. When the Vdara® hotel first opened in Las Vegas, visitors relaxing by the pool experienced intense periods of heat at certain times of the day and year. This intense heat was caused by the reflection of solar radiation from the curved reflective surface on the south-facing side of the hotel. (The issue has since been addressed and fixed.)

In this webinar, we will model how a caustic surface is generated in the hotel's pool area around the time and date the problems were first reported. During the live demo, we will use ray tracing and model the radiation from the apparent position of the sun based on the geographical coordinates of the location.
