Reply To: ANSYS fluent – Rocky DEM coupling

[Saeed]

the first time, i faced this issue i was doing one way coupling which i set the rotation my self. 

i also some time face this when i do the 2 way coupling , which the rotation is set by fluent , when i run the simulation with 100 RPM which is counterclockwise . I tried 260 RPM which was set by the fluent but it was clockwise. so I defined another motion exactly like the one that was set by fluent , but i changed the rotation to -260 to have counterclockwise. 

 

I did my trials with a case that was not coupled I just imported the walls and defined the motion and assigned it. what i saw was that above 220 or 230 the motion rotation chnages.
