Important

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 .

5. Examples

Here, the program library for E3DRH version 2 tiled will be used to:

• create an Octree mesh based on the survey

• create octree models

• predict frequency-domain airborne data for a synthetic model

• invert the data to recover our synthetic model
