Frequently Asked Questions (FAQ)

Posted by in MOAB

General What’s the largest mesh MOAB can read/write? We’ve read meshes of 128M tetrahedral elements and 256M hexahedral elements. For 64M tets, MOAB uses about 2.5GB of memory. MOAB also has a structured mesh representation, that requires about 57% less memory than the unstructured representation. Memory use does tend to vary depending on what you’re doing with the mesh, since...

Importing CUBIT files

Posted by in MOAB

CUBIT is a toolkit for generating tetrahedral and hexahedral finite element meshes from solid model geometry . This tool saves and restores data in a custom “.cub” file, which stores both mesh and geometry (and data relating the two). The CUB reader in MOAB can import and interpret much of the meta-data information saved in .cub files. The MOAB meta-data document describes the conventions used...
