Short summary
This research introduces a semi-structured conformal hexahedral mesh for three-dimensional magnetotelluric modeling. This enhances accuracy, efficiency, and flexibility, especially with local mesh refinement. Numerical tests confirm good accuracy and better results than standard meshes, validated against benchmark models. The codes effectively handle topography and complex zones, utilizing fewer nodes and elements to enhance modeling accuracy.
