4.1.1. Create OcTree MeshΒΆ
OcTree meshes used in the TDoctree version 2 code are created using the program create_octree_td_v2.exe. Parameters necessary for defining the OcTree mesh are set in the input file; referred to here as octree_mesh.inp.
To generate the OcTree mesh, open a command window. Type the path to the code create_octree_mesh_td_v2.exe, followed by a space, followed by the path to the input file.
The program create_octree_1mesh_td.exe creates 5 output files:
3D_mesh.txt: the underlying regular tensor mesh`. This mesh is comprised of the smallest cell size and is very large (>> 1M cells). As a result, it is unwise to plot this mesh.
3D_core_mesh.txt: A 3D regular tensor mesh defining the core region.
octree_mesh.txt: OcTree mesh used in the forward modeling and inversion codes
active_cells_topo.txt: active cells model on the OcTree mesh. Cells are active if assigned a value of 1 and inactive if assigned a value of 0
create_mesh.log: log file
