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.
