5.3. InversionΒΆ
Here, the code mtz3d.exe and the input file mt3dinv.inp (see format) are used to invert MT data. MT data were created in the example forward modeling and simple floor uncertainties of 0.005 V/A were added to all impedance tensor elements. In practice, data are noisy and choosing appropriate uncertainties is very important for successful inversion. Files relevant to this part of the example are in the sub-folder inv. Before running this example, you may want to do the following:
Download and open the zip folder containing the entire MTZ3D example (if not done already)

To invert the synthetic data, the following input file was used:
The true model (left) and recovered model (right) at iteration 4 are shown below. A cutoff of 0.05 S/m has been used for both models and the recovered model is transected at z = -1200 m.
