Hello Hi,

I am running a flow simulation inside a tube with throttle valve. In the problem, the boundary conditions are angle of throttle valve is from 0 to 90 in steps of 10. I just wanted to know whether the vavle rotates and just it is stationary at some angle.

I have attached the word file. Please let me know what to do..

First of all.

Do you know how to set up a NX Flow Simulation?

The steps you´ll have to do are.

1. Set up a Flow Simulation with your Boundary Conditions (BC´s) and use a Report/Lift´n´Drag to get the moment on your throttle valve.

2. Pressure Drop. There´s also a Report for the PD. If you need the PD from in- to outlet its easy to set up.

3. Postprocessing

4. If you want to transfer the forces into a FEM-Simulation you have to map the results. I have to look it up, how you can do it excatly, but theres also a tutorial in the NX help to do it.

Hope i could help a little
