IFOS3D (Inversion of Full Observed Seismograms) is a 3D elastic full waveform inversion code.
The inversion problem is solved by a conjugate gradient method and the gradients are computed in the frequency domain with the adjoint method.
The forward modeling is done by a time domain finite difference scheme.
IFOS3D is the reverse (inverse) of our 3D finite difference forward solver SOFI3D.
