Construct meshes from bulk mesh and geometries

General

constructMeshesFromGeometry is a conversion tool for the gml files. Given a “bulk” mesh and the gml geometry file the tool generates meshes for all named geometries.

The meshes are used for the boundary conditions and provide node ids and element ids mappings to the bulk mesh.

Example

For example a conversion of a mesh from Tests/Data/LIE/Hydromechanics single fracture 3D project:

constructMeshesFromGeometry -m single_fracture_3D.vtu -g single_fracture_3D.gml

debug: Reading geometry file '../s/Tests/Data/LIE/HydroMechanics/single_fracture_3D.gml'.
debug: Project configuration from file '../s/Tests/Data/LIE/HydroMechanics/single_fracture_3D.gml' read.
debug: The search length for mesh "single_fracture_3D" is 1.000000e-09.
debug: Creating mesh from geometry single_fracture_3D inlet.
debug: Found 3 elements in the mesh
debug: Creating mesh from geometry single_fracture_3D outlet.
debug: Found 3 elements in the mesh
debug: Creating mesh from geometry single_fracture_3D left.
debug: Found 46 elements in the mesh
debug: Creating mesh from geometry single_fracture_3D right.
debug: Found 46 elements in the mesh
debug: Creating mesh from geometry single_fracture_3D front.
debug: Found 1150 elements in the mesh
debug: Creating mesh from geometry single_fracture_3D back.
debug: Found 1150 elements in the mesh
debug: Creating mesh from geometry single_fracture_3D bottom.
debug: Found 25 elements in the mesh
debug: Creating mesh from geometry single_fracture_3D top.
debug: Found 25 elements in the mesh

yields new meshes for each named geometry: single_fracture_3D_inlet.vtu, single_fracture_3D_right.vtu, single_fracture_3D_outlet.vtu, single_fracture_3D_left.vtu, single_fracture_3D_front.vtu, single_fracture_3D_top.vtu, single_fracture_3D_bottom.vtu, and single_fracture_3D_back.vtu.

The figure shows the front part of the mesh with the extracted geometries. Note, the lower dimensional inlet boundary, shown as a line.
