A note on adjoint error estimation for one-dimensional stationary balance laws with shocks
Jochen Schütz, Sebastian Noelle, Christina Steiner +1
We consider one-dimensional steady-state balance laws with discontinuous solutions. Giles and Pierce realized that a shock leads to a new term in the adjoint error representation f…
On adaptive timestepping for weakly instationary solutions of hyperbolic conservation laws via adjoint error control
Christina Steiner, Sebastian Noelle
We study a recent timestep adaptation technique for hyperbolic conservation laws. The key tool is a space-time splitting of adjoint error representations for target functionals due…
Adaptive timestep control for nonstationary solutions of the Euler equations
Christina Steiner, Siegfried Müller, Sebastian Noelle
In this paper we continue our work on adaptive timestep control for weakly non- stationary problems. The core of the method is a space-time splitting of adjoint error representatio…
Timestep control for weakly instationary flows
Sebastian Noelle, Christina Steiner
We report on recent work on adaptive timestep control for weakly instationary gas flows [16, 18, 17] carried out within SFB 401, TPA3. The method which we implement and extend is a…
