Thanks for responding Weiguang, So would the workflow for this look something like: Open bct.vtp in Paraview > Identify node IDs > manually calculate u / v / w components for the angular velocity for each node >write to bct.dat file? For very dense meshes, this method would probably become very tedi...

I was wondering if there's a way to set up angular velocity as an inlet boundary condition? For example when trying to model the natural rotational component of cardiac flow through the aortic valve, do I edit parameters in the "initial velocities" section in the simulation sidebar? My understanding...

Chiming in to say that I'm having the same offset issue on Mac OS, any ETA on update?
