Example 1371: Generating an arbitrary 2D FEM mesh from nodes

The comfile run by this example is as follows:

FEM
FEM define nodes;r;example_1371;example     
FEM define window;c
FEM draw nodes

#defines a linear simplex basis
FEM define bases;r;;example    

#defines a mesh of 3 noded simplex elements from the defined nodes.
#A constraint on the maximum element size is applied. 
FEM define mesh;r;;example      
FEM draw lines
FEM draw nodes
FEM draw elements
refresh graphics

#refine elements 3,10,8,9 and increase minimum angle
FEM define refinement;r;refinement_1;example

FEM draw lines
FEM draw nodes
FEM draw elements
refresh graphics

#refine element 9
FEM define refinement;r;refinement_2;example

FEM draw lines
FEM draw nodes
