  ELLAM as a solver for convection-dominated transport problems
Thimo Neubauer (University Heidelberg)

Characteristic methods are very well suited for solving convection-dominated transport problems. One very promising scheme in this field is the Euler-Lagrangian localized adjoint method (ELLAM) which features global mass conservation and a natural way of including both Dirichlet- and Neumann-boundary-conditions.

In this talk we will give a short introduction to the ELLAM-scheme and a finite volume variant thereof (FV-ELLAM). We will then focus on the problem that both methods do not guarantee the monotonicity of the solution and discuss ways to reduce this error.
