Dear all,

I am intending to model helicopter downwash in Fluent.

Currently, I am using Ansys Student 18.1 (Free Version). 

I want to use the Virtual Blade Modeler to model the helicopter rotor as mentioned in the ansys fluent brochure.


It would be great if someone could direct me where I can get the tutorial/manual and the related UDF files for Virtual Blade Model Plugins.

Kind Regards,

Hi Nab,

The Virtual Blade Modeler referenced in the Fluent brochure was developed by a customer, Terrafugia to solve a specific problem, illustrating that such a plugin can be developed. This Virtual Blade Modeler is not a feature that we (ANSYS) provides for use with Fluent.  Here's the brochure reference in context:

  • "...In designing a roadable aircraft, Terrafugia developed a virtual blade modeler that plugged in to Fluent and created additional capabilities to model the aircraft’s propeller...." 

Terrafugia is developing some very interesting flying cars, see here: https://www.terrafugia.com/about-terrafugia/. You should feel free to reach out to them to ask about their Virtual Blade Model.  

Related, user "teymour" posted a VMB methodoligy and tutorial over on CFD-Online. The tutorial can be found here. 

Hope this helps.
