Example b21534: Collapsed elements

The standard Laplaces equation is solved on a mesh made up of 12 elements, four of which are cubes, eight of which are collapsed wedges, using collocation. The lattice based grid scheme is used.


The comfile run by this example is as follows:

fem define para;r;3dlaplace
fem define coor 3,1
fem define node;r;collapse
fem define base;r;3dlaplace
fem define elem;r;collapse
fem define grid;r;collapse
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
fem export node;collapse as geometry
fem export elem;collapse as geometry
fem export data;collapse lattice as grid
quit
