An approach to solve the elastic wave equation by adaptive finite elements is presented. The strategy for adaptivity is founded on an a posteriori residual-based error estimate, where the error is measured with respect to an arbitrary target functional, allowing to focus the simulation to the computation of a given quantity of interest. The cell-wise error indicators are computationally evaluated and used for refinement of the space-time mesh. The resulting grids are usually highly localized and tailored to the target functional. The performance of the approach is demonstrated with two examples.
