Hello,
I run
ffc Heat.form (See attachment please)
and I got Heat.py, but when I run
python Heat.py
I have no output.
How can I run heat equation?
Cheers

# The bilinear form a(v, u1) and linear form L(v) for

#
# Compile this form with FFC: ffc Heat.form
element = FiniteElement("Lagrange", "triangle", 1)
v = TestFunction(element) # Test function
u1 = TrialFunction(element) # Value at t_n
u0 = Function(element) # Value at t_n-1
c = Function(element) # Heat conductivity
f = Function(element) # Heat source
k = Constant("triangle") # Time step
a = v*u1*dx + k*c*dot(grad(v), grad(u1))*dx
L = v*u0*dx + k*v*f*dx
