Example 3151: Steady state heat distibution in a plate calculated using the laplace equation. Bicubic hermite elements

This family of example use the laplace equation to calculate the temperature distribution inside a plate using FEM. Bicubic hermite bases functions are used as the elements. Based on problem 311.

The comfile run by this example is as follows:

#Example_3151 Steady state temperature distribution in a plate (see example_3141).
#This example is used to test the convergence of the Laplace or Poisson equation
#The basis function is bicubic hermite.

fem                                        #Set the FEM environment
fem define parameter;r;lapcub1;example     #Defines the necessary parameters
