Example 316: Heat distribution in a plate using integrated point fluxes with bilinear elements

This example calculates the steady state temperature distribution inside a plate using FEM, with integrated point fluxes and bilinear elements.

The comfile run by this example is as follows:

#Example_316 Steady state temperature distribution in a plate (see example_111).
#This example uses point fluxes to enter intial conditions.
# 
fem                               #Set the FEM environment
fem define parameters;r;linear;example #Reads parameters needed to define the plate

fem define coordinates;r;;example #Reads in the coordinates used for the plate
fem define nodes;r;;example       #Reads in the nodes to define the plate
fem define bases;r;;example       #Defines a bilinear basis function
fem define elements;r;;example    #Reads in elements from file
fem define wind;c                 #Calculates the graphic window size
fem draw lines                    #Makes the line segments visible
fem draw nodes                    #Makes the node numbers visible
fem define equation;r;;example    #Defines a STATIC analysis of LAPLACE's 
#                                 !equation (STANDARD) using GALERKIN 
#                                 !FINITE ELEMENTS with LINEAR ANALYSIS
fem define material;r;;example    #Define material properties (none)
fem define initial;r;;example     #Defines initial conditions
#                                 !Three sides are held at zero and the forth
#                                 !side has a uniform heat flux of 1
fem list init                     #Write out the initial conditions
fem define solve;r;;example       #Defines solver options, default all settings
fem sol                           #Solves the boundary value problem
fem draw field                    #This will draw colour temperature field
fem draw contours label off       #Draws 10 contours step size 0.1 deg
