Benchmark 7 Mesh Generation

  A series of meshes of different resolution have been built to represent
the BM7 model domain. The grids above are available in AVS and GMV format.

See the image gallery for pictures of the mesh.

Build a 2D triangulation and smooth the triangles.

LaGriT Command File: bm7_cyl_pts2.lgi

OUTPUT: id_fault.inp

Note: The control file
Smooth the triangles:

LaGriT Command File: smooth.lgi

Input : id_fault.gmv
Output: s_r_mass1a.gmv

Stack the triangle layers to produce a tet mesh:

LaGriT Command File: stack.lgi

Input : s_r_mass1a.gmv
Output: cmo_settet.inp

Refine along the fault interface

LaGriT Command File: refine_tets.lgi

Input : cmo_settet.inp

Output :

refine_interface1.[ gmv / inp ]
refine_interface2.[ gmv / inp ]
refine_interface3.[ gmv / inp ]
refine_interface4.[ gmv / inp ]
refine_interface5.[ gmv / inp ]
refine_interface6.[ gmv / inp ]
