Detailed Description

2D HeatFlow 3x3 Spatial Discretisation

Author:

Bernard De Cuyper

Version:

1.15

Date:

14/08/2004

Remarks:

Tornado1 Spatial discretisation

2D Heat Flow 3x3

 
Purpose:        This 2D heatflow is more isotropic if c= 1/6

                This matrix is a block tridiagonal or or 9 band matrix

Notice:         c at 1/6 is more isotropic than c=0, but it is also more stable: 
                        the explicit limit is now at t=0.3, instead of 0.25!
