The Poisson demo would be good to do because it has both dx and ds integrals. KristianBoth. What would the Poisson demo look like with this feature?
element = FiniteElement("Lagrange", triangle, 1)
v = TestFunction(element)
u = TrialFunction(element)
x = triangle.x[0]
d_x = triangle.x[0] - 0.5
d_y = triangle.x[1] - 0.5
f = 10.0*exp(-(d_x*d_x + d_y*d_y) / 0.02)
g = sin(5.0*x)
a = inner(grad(v), grad(u))*dx
L = v*f*dx + v*g*ds
What should we call the demo, and where do we put it in DOLFIN?
