In order to improve the reliability and acceptability of any CFD calculation,  a CFD result should be always accompanied of an uncertainty bar.  Within ReFRESCO community since the beginning we have used code verification, solution verification, solution validation techniques (or usually called V&V techniques). And we have put lots of effort on pushing the usage of these techniques in all calculations, papers, thesis and workshops. In http://www.refresco.org/verification-validation/ we have created some pages with some basics on these techniques, and some useful websites with workshops dedicated to the theme. And now, finally, the tools developed in the last 10 years to analyze numerical uncertainty are being made available to the CFD community in general. Go to http://www.refresco.org/verification-validation/utilitiesvv-tools/ , download them, use them and please give us feedback!

Lets make CFD more reliable together…
