Abstract:
In this paper, a modified method of characteristics in combination with integral identities of triangular and tetrahedral linear elements is used to prove a uniform optimal-order error estimate which depends only on the initial data and right-hand side, but not on a scaling parameter $\varepsilon$, for multi-dimensional time-dependent advection-diffusion equations.
Key words:
modified method of characteristics, triangular linear element, tetrahedral linear element, integral identities, uniform error estimate.
