Multiple Reference Frame (MRF) models simplify the modeling of turbomachinery, allowing you to simulate with a steady-state model what would normally look to require a transient CFD simulation.
Those doing CFD post-processing from simulations of fans, pumps, stir tanks, HVAC, and other rotating machinery often want the parts to rotate. We have developed a specific tool to provide part rotation using the python scripting language. This tool provides rigid body motion according to several options you can provide. Combining rigid-body motion with pathlines provides a nice looking and logical recreation of the moving parts in your Multiple Reference Frame (MRF) CFD simulation.
A couple of frequent questions from users of EnSight are answered in this screencast such as:
– Can I make parts rotate or appear to rotate in EnSight
– I solved my CFD simulation using Multiple Reference Frame (MRF) – how do I use that in EnSight
– what is the difference between streamlines and pathlines
– how do I make pathlines
– what are some useful specialized tools that come with EnSight

This Rigid-body motion tool is found in standard EnSight 9 and EnSight 10, in the User-Defined Tools, Visualize section, Rigid-Body Motion.This video uses EnSight 9, but the same tool and process also works in EnSight 10. We just didn’t update the movie, since there was no need.
