WebMesh quality may ultimately be judged by the success of the resulting CFD run, but as a proxy various mesh quality indicators such as skewness and non-orthogonality can more easilly be evaluated. The signi cant point here is that this process may be regarded as a multi-parameter and probably multi-objective optimisation problem.
