Example two-patch model: two patches, both of size \(4\times 6\), are coupled at the common interface. Moreover, the left patch has a Dirichlet boundary condition on its left edge and the right patch has a Neumann boundary condition of \(f=1\)/unit on its left side. The quadratic patches have both 9 control (black points) and 4 quadrature points (blue crosses). For the integration along the edges 3 quadrature points (orange crosses) are used
