Example b/b2/b21/b215/b2153/b21512: 2d square

The standard Laplaces equation is solved on a 2d line using collocation where the elements are of different sizes. The lattice based grid scheme is used. Compare this example to b2132, which uses the older collocation grids.

The comfile run by this example is as follows:

fem define para;r;2dlaplace
fem define node;r;2dlaplace
fem define base;r;2dlaplace
fem define elem;r;2dlaplace
fem define grid;r;2dlaplace
fem update grid geometry
fem update grid metric
fem define equa;r;2dlaplace
fem define mate;d
fem update grid material
fem define init;d
fem define solv;r;2dlaplace
fem solve
