how do i change the refrence velocity to auto update to a corresponding inlet velocity. I'm running many simulations of a similar body across many velocities. It's a pain in the butt to update every time: the initial condition, the inlet velocity, and the drag coefficient "reference Velocity" normalizing factor. There's gotta be a way to code a short cut when i change one it'll change the others... help would be appreciated on the topic.

Make a report that gets the velocity (Mass flow averaged?) and then reference it in your drag coeff equation...

If the report is named "Velocity", you reference it via "$VelocityReport" without quotes of course.
