Hi @rtrowbridge!
I see you are using the Hex-Dominant Automatic meshing function. Normally I would typically use the Hex-Dominant Parametric meshing function for greater control at the points of interest.
With the automatic function it seems like the relative low quality of the mesh at the outlets (holes) is causing some problems for your results and I would recommend using the parametric function and refining the area near the holes to get a better resolution as currently it seems rather distorted.
I’ll mesh it out and see if it works, but in the meantime can you share how you verify your velocity? What would be considered the velocity that “makes sense” as you have mentioned?
I’ll play around with the results control to see if I am able to obtain out the values. For downloading your data and post-processing offline I think ParaView may be able to obtain our your flow rate and i’ll again get back to you on this.
Cheers,
Barry
