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...

Visualization with MOAB

Posted by in MOAB

Notes about VisIt 2.3.0 VisIt is a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms. It is widely used in various DOE labs and for other large simulations. VisIt has developed an ITAPS_MOAB reader that can be used to view .h5m (HDF5) and .cub(CUBIT) files. Follow these steps to build VisIt with ITAPS option: 1. Goto:...

Building MOAB

Posted by in MOAB

Prerequisites While MOAB can be built without these libraries, we strongly recommend getting at least HDF5. Netcdf: If you’d like to read Exodus files with MOAB, and to run MOAB’s ‘make check’, you’ll need  Netcdf. If it’s netcdf version 4 or greater, we recommend building without HDF5 (i.e. don’t use –enable-netcdf-4 configure option). We require...
