Velocity Results

Click the Results tab.

In this step, we examine the velocity results using a cutting plane and vectors.

Cut planes show results on a slice through the model. Use them to gain a comprehensive understanding of the flow. Use vectors to show the velocity direction and magnitude throughout the device.

Click Planes from the Results tab:

To create a Plane, click Add on the Planes context panel:

add plane

To orient the plane, left click on it, and click Z from the context toolbar:

To move the plane, drag the triad axis normal to the plane.

To display vectors, select Velocity Vector from the Vector menu on the Planes context panel:

To adjust the vector spacing:

  1. Click Edit on the Planes context panel.
  2. On the Plane Control dialog, drag the Grid spacing slider toward Fine. (This is near the bottom of the dialog.)

To display vectors with varying lengths (scaled with Velocity):

  1. Click the Vector settings tab.
  2. In the Length group, select Length range.
  3. Drag the Min slider to the left and the Max slider to the right.

To hide the contours, right click on the plane, and select Outline.

Move the cut plane near the symmetry face, and zoom in close to the poppet.

Note: You can see a region of recirculation behind the poppet. It is always a good idea to pay attention to these kinds of details in the flow. This is information that can help you make design decisions, but is not readily accessible with laboratory testing.
