I am following the tutorial on youtube: SolidWorks FL Tutorial #282 : PC Fan with flow simulation analysis - YouTube
The geometries can be found here 3D CAD Model Collection | GrabCAD Community Library.
Currently i encounter 2 problem : 1. When I reach the part where I need to insert a rotating region I seem to not be able to aim it at the negative Y axis. I tried putting negative RPM in the region but all it did was change the rotation direction rather than the axis.
2. Even ignoring the rotation region axis (leaving it positive RPM) I am getting an error saying Fluid Volume Recognition has failed, please check geometry.
Anyone know how I can fix this?
