Using Variability in Simulation: A Practical Workshop
Natural variability and randomness affect every real-world process, but how should their effects be included in simulations? Following on from the December 2011 NAFEMS seminar on “Why Simulation Needs To Consider Variability”, this workshop provided practical demonstrations of a range of available software tools; and methods for including variability in existing FEA and CFD models.
The workshop included an introductory lecture by a leading expert in the area; a “vendor challenge”, where software vendors showed how to apply their product to a problem defined by NAFEMS experts; a demonstration using Excel for a simple problem that attendees recreated on their own laptops; and material from a highly-regarded course was presented. NPL staff also hosted tours of their material property measurement laboratories and answered questions about measurement methods and uncertainties.
