Use a results plane to view the flow through a valve model.

After running a valve model simulation in Autodesk CFD,
00:07
you can use a results plane to visualize a two-dimensional flow through the model.
00:12
To create a plane, on the ribbon, Results tab, in the Results Tasks panel, click Planes.
00:20
Then, in the Planes context panel, click Add.
00:24
To rotate the plane, left-click it, and click Z from the context toolbar.
00:30
The orange regions near the top of the poppet indicate that the flow is accelerating through the gap.
00:36
The flow on the trailing side of the poppet appears to be recirculating, but you will be able to tell more when you look at vectors.
00:43
Also, as the flow turns toward the outlet, it accelerates off the inside corner.
00:49
To see the pressure drop through the valve, right-click the plane,
00:53
and select Result > Static Pressure to display a plot of static gage pressure.
00:59
In this example, the outlet boundary condition was set to 0 Pa gage, and everything in the plot is relative to that value.
01:08
Because the pressure is 0 at the outlet, the pressure at the inlet is the overall pressure drop.
01:14
Note that the pressure dips low as it turns the inside corner near the outlet but not low enough for cavitation to be an issue.

Using a results plane to visualize the flow through a valve model is just one of the ways to view simulation results in Autodesk CFD.
