1.1.8 Execute Tab

This tab is where the simulation is started and controlled.

• Click Execute at the top of the TransATUI

1.1.8.1 Starting the simulation
• Click to start the simulation

1.1.9 Viewing Results in Paraview

The results of the simulation can be seen with the help of the Open-Source Visualisation Tool,
ParaView.

• To launch ParaView, click Start and select All Programs > ParaView-4.0.1 > ParaView.

• click File − > Open.

• Navigate to the RESULT folder and choose xy-channel turbulent...vtm.
• Click Apply.

• Choose variable T from the drop-down list. (See Figure 1.4).

• Make visible the father object (xy-channel turbulent.0000*) by clicking on the ”eye”.

• Play the animation by hitting the Play button.

1.1.9.1 Plotting Velocity Vectors

To create velocity vectors in Paraview, an object is needed to calculate the 2D velocity vector,
and a plotting device to display the vector. To this end, the Calculator and the 2D Glyph tools
are used.

• In the same Paraview window, create a Calculator object by clicking in the toolbar.
Alternatively, select Filters − > Common − > Calculator in the menu bar to create a
Calculator

• In the Object Inspector window for the Calculator, enter Velocity as the Result Array
Name.

• In the box below, enter U ∗ iHat + V ∗ jHat. See Figure 1.5.
