CAD Integration and Automatic Meshing

	Posted Tue April 24, 2001 @12:32PM
	STAR-CD's Pro*am meshing tool uses a unique collection of hexahedral and "hybrid" cells to automatically generate a body fitted mesh. The subsurface is used to cut a block of hexahedral cells, leaving all cells untouched by the cutting surface as perfect hexahedra, and producing a variety of cell types where the surface cuts the block. ... The meshes produced in this way tend to be of high quality and are very suitable for CFD – in general over 90% of the cells are perfect hexahedra with no distortion. A cool idea, although it should be noted that the hexahedra will not be "flow aligned" and will, therefore, lose some of the accuracy that people usually associate with structured block grids.
