MOAB is a component for representing and evaluating mesh data. MOAB can store structured and unstructured mesh, consisting of elements in the finite element “zoo”. The functional interface to MOAB is simple yet powerful, allowing the representation of many types of metadata commonly found on the
... [More] mesh. MOAB is optimized for efficiency in space and time, based on access to mesh in chunks rather than through individual entities, while also versatile enough to support individual entity access.
MOAB implements the ITAPS iMesh interface; iMesh is a common interface to mesh data implemented by several different packages, including MOAB. Various tools like smoothing, adaptive mesh refinement, and parallel mesh communication are implemented on top of iMesh. [Less]
UG is a flexible software tool for the numerical solution of partial differential equations on unstructured meshes, with a focus on multigrid methods. It has a very powerful grid manager, which supports two- and three-dimensional grids with mixed element types. The grids can be adaptively refinement
... [More] using either classic red/green-refinement, or pure red refinement with hanging nodes. All this is fully parallelized and can run on large distributed machines.
UG supports many different discretization schemes. UG can be used through its built-in shell, using a special scripting language. It can also be used as a library from other finite element codes. [Less]
