We have investigated the use of the adaptive high-order finite-element method (FEM) for
geoelectromagnetic modeling. Because high-order FEM is challenging from the numerical …

We present a multi‐resolution finite‐element approach for three‐dimensional (3D)
electromagnetic (EM) induction modeling in spherical Earth. First, the secondary electric …

We present a robust and scalable solver for time-harmonic Maxwell's equations for problems
with large conductivity contrasts, wide range of frequencies, stretched grids and locally …

We have developed an open-source parallel 3D forward modeling code called EMFEM for
the frequency-domain electromagnetic method (FDEM). This code is based on the adaptive …

To effectively and efficiently interpret or invert controlled-source electromagnetic (CSEM)
data which are recorded in areas with the kind of complex geological environments and …

This work is devoted to the construction and analysis of robust solvers for some distributed
optimal control problems for time-periodic eddy current problems. We apply the …

Efficient 3-D magnetotelluric anisotropy forward modeling is one of the key research
