Estimating Grid-Induced Errors in CFD Solutions

The accuracy of CFD solutions depends not just on the validity of the physical models used such as those for turbulence and the fidelity with which the governing equations are represented in algebraic form but also on the mesh and the time-step size.  In fact, even a “perfect” CFD model, algorithm, and code that is executed in perfect fashion will generate solutions with significant errors if the grid or mesh is of poor quality.  This talk addresses methods that seek to estimate errors induced by the grid with focus on the Discrete Error Transport Equation.
