34  Solve the problem
35 
36  \partial_t u - \nu(t) \Delta u + sigma(t) u = f(t)
37 
38  u = g on the boundary
39  u(t=0) = u0 initial condition
40 
41  on a cube
42  \nu, \sigma and \source can be function of time
43  (which implies that the matrix needs to be reassembled each time)
44 
45  Purpose: Test BDF of different order
46 
47  The analytical solution used in the test is quadratic both in space and time.
48  Therefore a second order approximation in space + BDF2 should provide a solution exact up to
49  the tolerance of the linear system.
