On explicit error estimates for the elastic wave propagation in heterogeneous media

Résumé

This work deals with explicit a posteriori error estimates for elastic wave propagation in heterogeneous media. Based on some previous works on acoustic problems, the proposed explicit error estimator is derived in a non-natural Lâ norm by using several reconstructions of numerically calculated fields. The effectivity of the estimator on uniform meshes and adaptive meshes is studied numerically. The results indicate that the error estimator gives an upper bound to the true error. Improvements for the reconstruction in time and in space are proposed.
