We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi 

If Mass flow is not working, please try this expression, which is equivalent to the mass flow rate

MassFlow = areaInt((Velocity u * Normal X + Velocity v * Normal Y + Velocity w * Normal Z)*Density)@IsoClipName

Evaluate this expression to get the mass flow rate.
