*                                                                           *
*  This program creates very easily a structured 2D meshes with BCs.        *
*  The element types include 4, 5, 8, 9, 12 and 16-node rectangles and      *
*  3, 6 and 10-node triangles. There is also limited 3D functionality       *
*  with 8, 20 and 27-node cubes and 6-node prisms.                          *
*                                                                           *
*  The program may also be used as a mesh import and export utility. It     *
*  is able to read several different formats and writes mainly Elmer input  *
*  and output formats. The meshes may also be given some simple operations. *
*                                                                           *
*  Note: this software was initially part of my first fem implementation    *
*  the Pirfem code, then later called Quickmesh, and finally renamed to     *
*  Elmergrid. The code has never been designed and with new features the    *
*  code has eventually become very dirty and does not present my view of    *
*  good programming.                                                        *
