Turbulence modeling is one of the main sources of uncertainty in CFD simulations of technical flows. This is not surprising, as turbulence is the most complex phenomenon in classical physics.

Future Facilities has today launched Release 16 of its industry-leading Computational Fluid Dynamics (CFD) software and digital twin technology, 6SigmaDCX. The updates will deliver improved ...

Additionally, refining the model extends run time and often requires purchasing ... enabling two separate yet critical outcomes. First, Ansys software solved the CFD simulation significantly faster ...

Over at NASA, Michelle Moyer writes that the 2016 NASA Software of the Year Award has gone to Pegasus 5, a revolutionary CFD tool. Developed in-house by a team led by aerospace engineer Stuart Rogers ...
