ABSTRACT:


High order methods have great promise, among the most important being
the potential for improved computational efficiency and fidelity when
compared to low order methods. Unfortunately, the positive features of
high order discretizations, especially low dissipation, mean they often
lack the robustness needed for industrial level computations. In this talk,
I examine the features needed for a discontinuous Galerkin spectral element
method to be provably stable for the approximation of the nonlinear compressible
Navier-Stokes equations, features that make them suitable to compute complex
flows in arbitrary geometries of industrial interest.
