Template:Demo DNS Guidance

You are first asked to provide a brief review of the state of the art for this test case. Give a brief overview of the test case. Describe the main characteristics of the flow. In particular, what are the underlying flow physics which must be captured by the computations ? Give reasons for this choice (e.g. poorly understood flow physics, difficulty to predict the flow with standard turbulence models, ...). Detail any case-specific�c data that needs to be generated.
