2d square (using Grid-based FE)

Example b2139: 2d square (using Grid-based FE)

The standard Laplaces equation is solved on a 2d square using collocation where the elements are of different sizes.

Note: this example is identical to b2132 except that it uses the Grid-based Finite Element Method instead of Finite Differences.

The comfile run by this example is as follows:

fem define para;r;2dlaplace;example
fem define node;r;2dlaplace;example
fem define base;r;2dlaplace;example
fem define elem;r;2dlaplace;example
fem define grid;r;2dlaplace;example
fem update grid geometry
fem update grid metric
fem define equa;r;2dlaplace;example 
fem define mate;d
fem update grid material # (only use this line for standard laplace)
fem define init;d
fem define solv;r;2dlaplace;example
#fem solve

Additional testing commands:

fem solve
