E3D version 2 tiled package

Important

E3D version 2 tiled performs forward modeling and inversion with the executable e3d_v2_tiled.exe. Past iterations of this code may have been given the name ‘AEM.exe’, although its application is not limited to airborne. To use this code, ensure you have downloaded the E3D version 2 tiled package from the UBC-GIF website.

E3D version 2 tiled is a program library for carrying out forward modelling and inversion of frequency domain EM data over 3D structures. Unlike E3D version 2, the E3D 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:
