On the non-symmetric coupling method for parabolic-elliptic interface problems
Herbert Egger, Christoph Erath, Robert Schorr
We consider the numerical approximation of parabolic-elliptic interface problems by the non-symmetric coupling method of MacCamy and Suri [Quart. Appl. Math., 44 (1987), pp. 675--6…
On structure-preserving model reduction for damped wave propagation in transport networks
Herbert Egger, Thomas Kugler, Björn Liljegren-Sailer +2
We consider the discretization and subsequent model reduction of a system of partial differential-algebraic equations describing the propagation of pressure waves in a pipeline net…
On the uniqueness of nonlinear diffusion coefficients in the presence of lower order terms
Herbert Egger, Jan-Frederik Pietschmann, Matthias Schlottbom
We consider the identification of nonlinear diffusion coefficients of the form or in quasi-linear parabolic and elliptic equations. Uniqueness for this inverse prob…
Energy stable discretization of Allen-Cahn type problems modeling the motion of phase boundaries
Anke Böttcher, Herbert Egger
We study the systematic numerical approximation of a class of Allen-Cahn type problems modeling the motion of phase interfaces. The common feature of these models is an underlying…
An asymptotic preserving mixed finite element method for wave propagation in pipelines
Herbert Egger, Thomas Kugler
We consider a parameter dependent family of damped hyperbolic equations with interesting limit behavior: the system approaches steady states exponentially fast and for parameter to…
