Risk Reduction

Organizations want to rely more on simulation to predict the behavior of complex systems​

This requires results that are accompanied by a measure of confidence that is informed by understanding the uncertainties in the simulation process and ideally, validated by experiment.

“within 95% confidence, the drag is between 17.5 and 18.7”

For some, there is insufficient experience and test data to validate the CFD results and assess their applicability.  There may be experiment or flight test data for which tolerances and provenance is suspect or unknown.

Every CFDer knows that there are causes of uncertainties in simulation methods, even with DNS

Can I trust in my analysis? Boundary Conditions? Mesh Quality?

Can I find and reliably use test data and simulation results?

Are my competitors gaining with new technology that we can’t seem to use?
