Adding Streamlines

Streamlines can be added into any of the scalar or geometry scene plots with the creation of a `streamline' derived part.

In the heatedFin window, right-click on the Derived Parts node and select New Part > Streamline...

A new interactive in-place dialog, Create Streamline, will appear on top of the Graphics window to allow definition of the derived part.

Click the Input Parts button.

Make sure that Fluid is the only part in the Selected list and then click Close.

In the Vector group box, make sure that Velocity is selected in the drop-down list. For the seed mode, select Line Seed.

Activate the display tool option by ticking its checkbox, and set the resolution to 15.

Hide the Create Streamline dialog using the arrow button at the bottom left; then, using the spheres at each end of the tool, adjust the line so that it is approximately half a cell above the top of the solid fin. To adjust the line, simply select either sphere and move it using the mouse.

Show the Edit Streamline dialog and then click Create to produce the streamlines.

The streamlines will be generated and shown in the display (this may take a few seconds).

In the heatedFin window, a new node will appear within the Derived Parts node: streamline.

Click Close in the dialog.

The streamline part can now be added to any suitable scene or be displayed in its own scene if desired. We will create a new scalar scene and color the lines with the temperature scalar value.

Right-click on the Scenes node, and select New Scene > Scalar

Right-click on the scalar bar in the display.

In the pop-up menu that appears, select Temperature.

By default, Fluid and Solid are included in the scene. We will remove these and display the streamlines only.

In the object tree, select the Scenes > Scalar Scene 2 > Displayers > Scalar 1 > Parts node.

In the Properties window, click on the right half of the Parts property

Make sure that only streamline is in the Selected list.

Click Close.

Streamlines colored according to the local temperature will appear in the Scalar Scene 2 display.
