Example b21533: 3d cube

The standard Laplaces equation is solved on a 3d cube mesh using collocation where the elements are of different lengths. The lattice based grid scheme is used. Compare this example to b2136, which uses the older collocation grids.

The comfile run by this example is as follows:

fem define para;r;3dlaplace
fem define coor 3,1
fem define node;r;3dlaplace
fem define base;r;3dlaplace
fem define elem;r;3dlaplace
fem define grid;r;3dlaplace
fem update grid geometry
fem update grid metric
fem define equa;r;3dlaplace
fem define mate;d
fem update grid material
fem define init;d
fem define solv;r;3dlaplace
fem solve
