Comparing many different CFD cases is often complicated by the use of differing meshes, solver codes and time intervals. Intelligent Light is working with CFD users in industry to develop and demonstrate engineered workflows to support the direct comparison of varied data.
The helicopter community seeks quality methods that allow for cost effective, accurate and timely simulations of hovering flight. The Helicopter Hover Prediction Workshop 2016 provides an opportunity to apply a standardized, automated post-processing workflow that eases dataset comparison, report generation and knowledge extraction for a diverse set of CFD results derived from varied models and solvers.
Dr. Earl P. N. Duque, Intelligent Light's Manager of Applied Research and Yves-Marie Lefebvre, FieldView Product Chief participated in the European Rotorcraft Forum September 5-8, 2016, in Lille, France. Dr. Duque presented in the aerodynamics track and the CFD workflow that enabled the work has applications for all CFD users.

Direct comparisons of the CFD simulation results and the standardized post-processing scheme based upon FieldView will be demonstrated.The workflow tracks the helicopter rotor tip vortex core for quantitative comparisons while Iso-surfaces and coordinate cut planes of Q-criterion were created and saved as FieldView XDB files for qualitative comparisons. These surface extracts allow interactive viewing and direct comparisons of the predicted wakes using multi window graphical displays.
