Example 131: Generating a 2D mesh of squares

This example uses the define mesh command to create a 2D mesh of squares.

The comfile run by this example is as follows:

#Example_131  Generating a 2D mesh of squares
 
fem
fem define bases;r;squaremesh;example   #defines a bilinear basis function
fem define mesh;r;squaremesh;example    #define a regular mesh with even
#                                   !  spacing and two elements in each
#                                   !  direction.
fem define window;c                 #open a graphics window to fit the
#                                   !  mesh.
fem draw nodes                      #draw the node numbers in their
#                                   !  positions on the mesh.
fem draw elements                   #draw the element numbers.
fem draw lines                      #draw the element lines.

Additional testing commands:
