Plotting Contours

The remaining sections of this tutorial cover the definition and display of various plots that help to visualize the solution just obtained.

The first plot to be drawn is a contour plot of temperature on the surface of the mixing pipe. To create this plot:

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

Select the Scalar Scene 1 > Displayers > Scalar 1 > Parts node

In the Properties window, click on the right half of the Parts property to display the Select Objects dialog

Select those parts corresponding to boundaries (Fluid:inlet, Fluid:inlet2, Fluid:outlet, Fluid:wall) and then click Close.

Select the Scalar 1 displayer node

In the Properties window, click on the right half of the Contour Style property and then select Smooth Filled from the pop-up menu

Select the Scalar Field node and, in the Properties window, open the pop-up menu of the Function property

Select item Temperature from the list of variables displayed

After some rotation and repositioning of the geometry, the results should appear as shown below.

Now plot contours of velocity magnitude on an x-z plane passing through the origin. One way of doing this is as follows:

Right-click on the Derived Parts node and select option New Part > Plane Section

A new interactive in-place dialog (Create Section) appears on the left of the Graphics window to help you define the desired plane. In this dialog:

Click Input Parts and then select Fluid from the corresponding Select Object dialog

Enter appropriate parameters specifying the desired plane, as shown in the figure below

Click Create

Note that a new node, plane section 2, will now appear as an additional Derived Parts constituent.

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

Select the Scalar Scene 2 > Displayers > Scalar 1 > Parts node and, in the Properties window, click on the right half of the Parts property to display the Select Objects dialog

Select only the plane section 2 part created above and then click Close

Click on the right half of the Contour Style property and select Smooth Filled from the pop-up menu

Right-click on the scalar bar that appears in the Graphics window and select Velocity: Magnitude in the pop-up menu displayed

After some rotation and repositioning of the mesh, the results should appear as shown below.
