5.1.1. Create OcTree Mesh

Here, the code create_octree_mesh_e3dmt_v2.exe and the input file octree_mesh.inp (ref:see format<e3dmt_input_octree>)are used to create an OcTree mesh based on the set of observation location and surface topography. Files relevant to this part of the example are in the sub-folder octree_mesh. Before running this example, you may want to do the following:

• Download and open the zip folder containing the entire E3DMT version 2 example (if not done already)

• Learn how to run code from command line

• Learn the format of the input file

To generate the OcTree mesh, the following input file was used:

The surface topography and resulting OcTree mesh are shown below
