Plots

This section shows some of the common plots used in the simulation. The steps to create the plots are:

1. Click Load Results in the Simulation Panel.
2. Select the required result file in the ensuing Load Results dialog box, click Open.

Pressure Force

The force exerted by the pressure in flow direction over the truck body, is monitored by plotting the net Pressure Force X. Plot the pressure force on the surfaces of the truck as follows:

1. Select CAB, TIRE_1, TIRE_2, TIRE_3, TIRE_4, TIRE_5, TIRE_6, TIRE_7, TIRE_8, TIRE_L_1, TIRE_L_2 and TRAILER boundaries under Volumes in the Geometric Entities Panel.
2. Click Add XY-Plot in the Toolbar.
3. Click Click for Variable List in Plot Panel toolbar, select Pressure Force X from Flow list.
4. Click Combine Entity Data into a Single Curve to obtain the net pressure force.

Shear Force

To plot the shear force X on the surfaces of the truck do the steps as follows:

1. Select CAB, TIRE_1, TIRE_2, TIRE_3, TIRE_4, TIRE_5, TIRE_6, TIRE_7, TIRE_8, TIRE_L_1, TIRE_L_2 and TRAILER boundaries under Volumes in the Geometric Entities Panel.
2. Click Add XY-Plot in the Toolbar.
3. Click Click for Variable List in Plot Panel toolbar, select Shear Force X from Flow list.
4. Click Combine Entity Data into a Single Curve to obtain the net shear force.

Drag Coefficient

To plot the drag force and drag coefficient do the steps as follows:

1. Select Common in the Model Panel.
2. Click Add XY-Plot in the Toolbar.
3. Click Click for Variable List in Plot Panel toolbar and then select Drag force or Coefficient_of_Drag from Common list.
4. Click Plot Selected Variables .
