Homework Help: Boundary value problem: local stifness matrix

  1. Dec 27, 2009 #1
    1. The problem statement, all variables and given/known data

    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))

    2. Relevant equations

    3. The attempt at a solution

    Does anyone know where i can start?

    I am using the finite element method.
    I forgot to mention, i fixed my problem, i know how to do this question :)
