Abstract |
Gauss-Lobatto spectral elements, based on hexahedral meshes, provide, in their mixed formulation, a very efficient way to solve transient wave equations in terms of storage and of computational time. Numerical experiments will be provided to illustrate their efficiency. In a second part, we deal with the problem of spurious modes and propose a cheap way to get rid of them. In a third part, we describe different strategies for hybrid meshes composed of hexahedra and tetrahedra, more useful to treat complex geometries. |
