About this event
In this livestream, we'll discuss energy stability for linear advection with variable advection speeds. This scenario arises when velocity fields depend on space and time and when isoparametric elements are used. Artificial dissipation, over-integration, and split-form equations are all methods used to mitigate the effects of aliasing errors. We'll discuss the split-form equations and present evidence in 1-D how this formulation maintains stability. In the coding portion of the livestream, we'll modify the conservative form previously implemented to add the "stabilizing terms" of the split form method.
