    [T] 2D Robin BC tests; Newton and Picard · 97fc351b

    A method of manufactured solutions is used to verify implementation of
    the Robin-type boundary condition. Grid convergence was assessed and the
    observed order of convergence is 1.99, which, as expected, is close
    enough to 2.
    
    In the same setup a Neumann and Dirichlet-type boundary conditions can
    (and were) tested with same convergence order as the Robin-type BC.
    
    The test is testing both non-linear solver schemes, Newton and Picard.
    With the new implementation of the Robin-type BC the convergence rates
    of the non-linear solver are satisfying, usually 2 iterations per time
    step for both schemes.
