An Optimal-Order Error Estimate to ELLAM Schemes for Transient Advection-Diffusion Equations on Unstructured Meshes
@article{Wang2010AnOE, title={An Optimal-Order Error Estimate to ELLAM Schemes for Transient Advection-Diffusion Equations on Unstructured Meshes}, author={Kaixin Wang and Hong Wang}, journal={SIAM J. Numer. Anal.}, year={2010}, volume={48}, pages={681-707} }
The Eulerian-Lagrangian localized adjoint method (ELLAM) provides a general characteristic procedure for solving transient advection-diffusion equations with general boundary conditions in a mass-conservative manner. In this paper we prove an optimal-order error estimate in the $L^2$ norm and a superconvergence estimate in the energy norm for the ELLAM scheme to $d$-dimensional transient advection-diffusion equations with general flux boundary conditions on unstructured meshes.
