mesh

       'mesh' <set> ['duns']

This keyword is used to start the meshing of the model. The element types must be defined before with the command elty. Already existing elements will not automatically be deleted. Therefore its possible to start cgx in the viewing mode (-v) with a mesh alone, then to create bodies and fill them with additional elements to create an extended mesh. To delete a mesh use the command del mesh. In case a structured grid for cfd-calculations should be generated use the command
mesh setname duns
Only entities included in the specified set are considered. A file with the grid (duns.grid) and the connectivity (duns.conn) will be created. See also the command ``send'' to describe areas for boundary-conditions and the section ``Remarks concerning duns''. Usually all elements are generated in a structured way. That means that no holes in a surface or volume are permitted. The only exception is the element type ``tr3u``. This type is generated in an unstructured way using the mesher from [11]. In this case holes are permitted and a surface comming from a cad system should be meshable. But unfortunatelly it works not for all possible combinations of divisions or all possible shapes of surfaces so far. Also the surface MUST reference a given NURBS-surface to be meshable. This is usually the case if the data are derived from a cad-system with the interface-programs (vda2fbd).
