Highlights

Many advancements have been made since the creation of the original tensor code (MTZ3D ). Hightlights include:

• the ability to model both magnetotelluric impedance data and Z-axis tipper data on an OcTree mesh

• joint inversion of magnetotelluric and Z-axis tipper data

• the ability to solve linear systems with iterative or direct solvers
