Uncertainty Quantification

Quantification of operating conditions, geometrical shape and manufacturing tolerances

 

With NUMECA’s automated Uncertainty Quantification (UQ) module, designers now have the capability to easily quantify the effect of uncertainties on CFD results. Through an intuitive interface, the UQ module allows users to set input parameters' uncertainty prescribed by arbitrary PDFs, combine them and analyze its effect on the solution.

Using the UQ will allow you to reduce the risks associated with your simulation based design decision process, by:

  • Specifying input uncertainties as probability density functions (pdf)
  • Running the fully automated chain from simulation set-up, geometry modification, meshing and post-processing
  • Obtaining predicted quantities with uncertainty bars 
  • Obtaining predicted quantities as probability density functions, instead of single values, defining hereby a range of confidence 

 

Key features

  • Easy-to-use UQ specific menu
  • Quantify the influence of operational, geometrical and manufacturing uncertainties
  • Pre-defined or user-defined probability density functions can be used for each uncertainty
  • Results with error bars for performance maps for turbomachinery, resistance curve for ships, flight envelopes for aircrafts and many more
