Hi all,
This week at SPAMS we have Per-Olof Persson, who will be talking
about the Discontinuous Galerkin Method. The talk will be held at 5pm
on Thursday in 2-139, and will be followed by Indian food in the
Applied Math Common Room.
Hope to see you then,
Chris, Pak, Kevin,
The SPAMS Organizers.

Title: The Discontinuous Galerkin Method
Abstract: The latest hype in computational PDEs is called the
Discontinuous Galerkin Method (or "DG"). It can be seen as a
combination of the popular finite element and finite volume methods,
and it is particularly successful for solving wave propagation and
convection dominated problems. The solution is represented in a
piecewise discontinuous basis, and the discretization is stable for
arbitrarily high polynomial orders. The domain is discretized by
unstructured meshes (for example with simplex elements), which makes
it geometrically flexible and allows for local adaptation.
I will talk about numerical solution of PDEs in general and give an
informal introduction to the DG method. I will show the benefits of
high order discretizations and unstructured meshes, and illustrate
with examples ranging from simple scalar problems to the full
unsteady compressible Navier-Stokes equations.
