Adding Streamlines
Streamlines can be added into any scene by creating a `streamline' derived part.
A new interactive in-place dialog will appear on the right of the Graphics window to allow definition of the derived part.
- Make sure that is selected in the Input Parts box.
- In the Vector Field group box, ensure that is selected in the drop-down list.
- For the Seed Mode, check that is selected, as shown above.
- Select from the Seed Part list and click Create
This creates streamlines originating at the methane inlet.
- Now select from the Seed Part list and in the Display section.
- Click Create again.
This creates a new set of streamlines originating at the air inlet.
- Click Close.
- Right-click on the scalar bar in the display.
- In the pop-up menu that appears, select
The display should then look as shown below.
The high cell density near the center of the inner inlet means that streamlines starting at this boundary are all bunched together.
- To rectify this, we can randomize their starting positions by opening the Derived Parts and streamline nodes and selecting the Source Seed node.
- In the Properties window, turn on the Randomize property. The final streamline plot is shown below.
- Save the simulation.
