Example 133: Generating a circular BEM mesh

This example uses the 'define mesh' command to create a 2D circular BEM mesh (ie using line elements).

The comfile run by this example is as follows:

#Example_133  Generating a circular BEM mesh
 
fem
fem define base;r;circbemesh;example   #define a BE Lagrange/Hermite basis
#                                  !  function with one Xi direction.
fem define mesh;r;;example             #define a circular BE mesh with 20
#                                  !  elements.
fem define window;c                #open a graphics window to fit the
#                                  !  circular mesh.
fem draw nodes                     #draw the node numbers around the
#                                  !  mesh.
fem draw lines                     #draw the element lines.
fem draw elements                  #draw elements.
#                                  !  Note that for the BEM mesh the
#                                  !  elements lie around the
#                                  !  circumference of the circle.
#                                  !  Compare this with the circular
#                                  !  FEM mesh in example_132.
