4.1.1. Create OcTree Mesh¶
OcTree meshes used in the E3D version 2 code are created using the program create_octree_mesh_e3d_v2.exe. Parameters necessary for creating the OcTree meshes are set in the input file; referred to here as octree_mesh.inp.
To generate the OcTree meshes, open a command window. Type the path to the code create_octree_mesh_e3d_v2.exe, followed by a space, followed by the path to the input file.
The program create_octree_mesh_e3d_v2.exe creates 5 output files:
3D_mesh.txt: the underlying tensor mesh for the OcTree 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 tensor mesh defining the core region of the OcTree mesh.
octree_mesh.txt: the OcTree mesh.
active_cells_topo.txt: an active cells model which defines the topography on the OcTree mesh. Cells are active (underground) if assigned a value of 1 and inactive (in the air) if assigned a value of 0.
