On the structure preserving high-order approximation of quasistatic poroelasticity
Herbert Egger, Mania Sabouri
We consider the systematic numerical approximation of Biot's quasistatic model for the consolidation of a poroelastic medium. Various discretization schemes have been analysed for…

A second order finite element method with mass lumping for wave equations in
Herbert Egger, Bogdan Radu
We consider the efficient numerical approximation of acoustic wave propagation in time domain by a finite element method with mass lumping. In the presence of internal damping, the…
