Homework Statement



Given a BVP:

[tex]\Delta(u)+u=1[/tex] in [tex]\Omega[/tex]
u=0 on [tex]\partial\Omega[/tex]
using linear piecewise functions,
calculate the corresponding local stiffness matrix on the reference triangle :
{(x,y); 0<=x<=1, 0<=y<=1-x}.

The domain is a square with one point in the middle (at (0.5,0.5))
