Makeup 02: inconsistent initial conditions

[orbeckst]

The problem description states as initial conditions T(x, 0) = T_min.

However, the tests are based on a solution that implemented

• T(0, 0) = T_min
• T(x, 0) = T_in for x > 0 i.e.,

    # initial conditions
    T[1:-1] = Tin
    # boundary conditions
    T[0] = T_diurnal(0, Tmin, Tmax)
    T[-1] = Tin

This made it difficult to get the TestCrankNicholson_T.test_solution test to pass.

@ianmkenney : when grading Makeup 02 then it will be ok if students

• implemented the initial conditions from the PDF (i.e. all Tmin)
• implemented the initial conditions that make the tests pass
