Modeling electromagnetics on cylindrical meshes with applications to steel-cased wells

Depth slice (left) and cross section (right) through the 3D cylindrical mesh used for the comparison with . The source and recievers are positioned along the \theta = 90^\circ line. The mesh extends 3600m raidally and 3300m vertically to ensure that the fields have sufficiently decayed before reaching the boundaries.
