Water flow measurement in Cylinder

Dear All,

I also want to design a Cylinder in which i can do water flow measurement in HFSS. Basically I have placed two antenna in a Cylinder i want to detect flow of water as water flow S21 and S11 will be change. So i just want to know how can i make water flow in HFSS.

You can't do flow down the tube in HFSS. Ansys Fluent can be used for flow, but I don't think you can integrate the solutions.
You can do a parametric sweep for static cases with different water levels. Assign a variable to the coordinate system value that you used to split the cylinder, and use that as your parametric sweep variable.

Check out COMSOL Multiphysics - but reidintransit's idea is best if you only have HFSS.
