    anisotropic Boundary conditions Free surface planar Absorbing boundaries Grid type Rectangular regular Solution type Numerical Total hits 5887 Additional resources All Releases Change logs Project Description FD3S AD is an extension of FD3S see above that allows to compute the derivative of an objective functional defined on a recorded seismic wavefield with respect to the model parameters Typical parameters are seismic wave speeds elastic constants or density The choice of the objective functional is made through the adequate definition of adjoint sources Since the computation of the derivatives is based on the adjoint method three wavefield simulations are needed 1 Computation of the forward wavefield The forward wavefield recorded at specified receiver locations is computed with a slightly modified version of FD3S In the course of the simulation the wavefield at the absorbing boundaries is stored in order to allow the reverse time stepping 2 Computation of the adjoint field The adjoint wave field is set off by the adjoint sources which have to be defined by the user on the basis of his or her choice of the objective functional The adjoint field also satisfies the elastic wave equation However it is anti causal meaning that it propagates from
