Mesh-Oriented datABase

OpenMC

An open-source Monte Carlo code for neutron and photon transport.

EntitySet

An arbitrary collection of entities in MOAB, including other EntitySet's. Parent-child relationships between EntitySet's can also be established. Synonymous with the term MeshSet.

MeshSet

A collection of entities in MOAB. Synonymous with EntitySet.

Tag

A named data field that can be associated with entities in MOAB. Each tag has an immutable data type. The size of the data can be fixed or variable.

GPRT

General Purpose Raytracing Toolkit

XDG

Accelerated Discretized Geometry

subdomain

A region of a mesh that is bounded by surfaces. In the context of XDG, a subdomain is a region of a mesh that is bounded by surfaces that are treated as interfaces between different materials. Also refferred to as a mesh block.

libMesh

A C++ finite element library that provides a framework for the development of parallel adaptive finite element methods.
