Abstract:
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.
