In the spring of 2022, a new suite of FDEM OcTree codes were compiled: E3DRH, E3DRH v2 and E3DRH v2 tiled. These codes use a right-handed coordinate system; as opposed to the modified left-handed coordinate system used by E3D, E3D v2 and E3D v2 tiled. You are currently viewing the manual for the package which uses ‘e3drh_v2_tiled.exe’ to forward model and invert FDEM data. The manual for the original E3D v2 tiled package (which uses ‘e3d_v2_tiled.exe’) can be found here .

E3DRH version 2 tiled package

E3DRH version 2 tiled is a program library for carrying out forward modelling and inversion of frequency domain EM data over 3D structures. Unlike E3DRH version 2, the E3DRH version 2 ‘tiled’ code performs the forward modeling in parallel on a set of local OcTree meshes. The contents of this manual are as follows:
