# What is IFOS2D?
**IFOS2D** (**I**nversion of **F**ull **O**bserved **S**eismograms) is a 2D elastic full waveform inversion code.
The inversion problem is solved by a conjugate gradient method and the gradients are computed in the time domain with the adjoint method.
The forward modeling is done by a time domain finite difference scheme.

The aim of full waveform tomography is to find an ''optimum'' model which can explain the data very well. It should not only explain the
first arrivals of specific phases of the seismic wavefield like refractions or reflections, but also the amplitudes which contain information
on the distribution of the elastic material parameters in the underground. To achieve this goal three problems have to be solved:
