An efficient mixed finite element method for nonlinear magnetostatics and quasistatics
Herbert Egger, Felix Engertsberger, Bogdan Radu
We consider systems of nonlinear magnetostatics and quasistatics that typically arise in the modeling and simulation of electric machines. The nonlinear problems, eventually obtain…
An asymptotic-preserving discretization scheme for gas transport in pipe networks
H. Egger, J. Giesselmann, T. Kunkel +1
We consider the simulation of barotropic flow of gas in long pipes and pipe networks. Based on a Hamiltonian reformulation of the governing system, a fully discrete approximation s…
A fast and oblivious matrix compression algorithm for Volterra integral operators
Jürgen Dölz, Herbert Egger, Vsevolod Shashkov
The numerical solution of dynamical systems with memory requires the efficient evaluation of Volterra integral operators in an evolutionary manner. After appropriate discretisation…
A mass-lumped mixed finite element method for acoustic wave propagation
H. Egger, B. Radu
We consider the numerical approximation of acoustic wave propagation in the time domain by a mixed finite element method based on the BDM1-P0 spaces. A mass-lumping strategy for th…
