CUBIT Meshing Program CUBIT is a toolkit for robust and unattended generation of two- and three-dimensional finite element meshes (grids). Our main goal is to reduce the time it takes to generate meshes, particularly large hex meshes of complicated, interlocking assemblies. CUBIT's areas of focus can be divided into three: geometry, meshing, and mesh quality.
	Mesh Cutting Technology Time to mesh from clean geometry: ~ ½ day Number volumes induced: 18 Number elements needed: ~18K hexes Min quality: 0.2020 scaled Jacobian

Areas of Research:

• Geometry - One of CUBIT's strengths is its geometry module, for changing the underlying solid model into the model you wish to mesh.

• Meshing - CUBIT is a solid-modeler based preprocessor that meshes volumes and surfaces for finite element analysis. Mesh generation algorithms include quadrilateral and triangular paving, 2d and 3d mapping, hex sweeping and multi-sweeping, tet meshing, and various special-purpose primitives. Our smoothing algorithms are state of the art and are incorporated into volume sweeping. CUBIT contains many algorithms for controlling and automating much of the meshing process, such as automatic scheme selection, interval matching, sweep grouping, and sweep verification.

• Mesh Quality - CUBIT incorporates many different methods of optimizing the nodal locations
  of a finite element mesh, in order to provide differing levels of quality of meshes for different applications.
