 When available, rigorous verification via formal order of accuracy assessment by exact or manufactured solutions is performed. When exact or manufactured solutions are not available, code-to-code comparisons are made. By comparing SU2 results against many well-established codes on a sequence of refined grids and seeing agreement of key quantities in the limit, we can build a high degree of confidence that the models found within SU2 are implemented correctly.
 
-We will continue to add cases over time to demonstrate V&V of additional physical models in SU2.
