64 Bricks
This is a simple geometry consisting of 64 geometric bricks arranged in a 4x4x4 lattice (in the figure above each geometric volume is a different color). 64 different material sets are allocated, along with 3 Dirichlet sets and 3 Neumann sets. Meshes consisting of hexes and tets have been generated for this model.
‘cub’ refers to meshes stored in CUBIT .cub format, ‘h5m’ to files stored in MOAB .h5m format.
Partitioned files were partitioned using Zoltan, using a Recursive Inertial Bisection (RIB) algorithm; parts consist of elements only and are stored as entity sets in the h5m file (tagged with PARALLEL_PARTITION tag; see MOAB user’s guide for details.)
These meshes were generated with the CUBIT mesh generation tool, based on this journal file. This generates the geometry stored here (ACIS .sat file) and here (STEP file).
