Example b21531: 1d line

The standard Laplaces equation is solved on a 1d line using collocation where the elements are of different lengths. The lattice based grid scheme is used. Compare this example to b2131, which uses the older collocation grids.

The comfile run by this example is as follows:

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