How to define a starting model constraint with VOXI that you can use in forward modelling or to enable an inversion to reach a faster optimal result.
How to define a starting model constraint with VOXI that you can use in forward modelling or to enable an inversion to reach a faster optimal result.
Use this focusing constraint to improve a simple unconstrained inversion to overcome the "non-uniqueness" problem in geophysical modelling.
Learn how to specify the fit error value which influences the difference between the measured and predicted data and how the inversion will fit the data.
Export VOXI Earth Modelling inversion results into 3D maps and databases
Compare inversion results to the measured data, simplify your interpretation process and iterate on models efficiently with the available tools
This video shows how to run a forward model using VOXI to generate the calculated potential field magnetic or gravity response of a given geophysical voxel model.
Runtime: 3:23
This video shows how to set up an inversion and is a prerequisite for watching the other how-to inversion videos listed below. The steps in this video include loading the VOXI menu, setting up a new VOXI session, and adjusting the parameters required to run an inversion. After watching this video, we recommend watching our other videos on running inversions.
Runtime: 5:00
In this video you’ll see how to add or modify data your model and run an unconstrained inversion.
Runtime: 6:05
