Example 3152: Steady state heat distibution in a plate calculated using the laplace equation. Refined once

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 This is the same as problem 3151 with Xi refined once in each direction.

The comfile run by this example is as follows:

#Example_3152 Steady state temperature distribution in a plate (see example_3141).
#This example is used to test the convergence of the Laplace or Poisson equation
#This example is example_3131 refined once per Zhi. The basis function is bicubic hermite.
