This example shows how to set up and run the simulation of a Jet Pump using VR. It demonstrates the use of the duplication facility and how to rotate objects. The flow is two-dimensional and its geometry is shown below. Velocity and pressure will be solved.

De-select the last object created by clicking on 'Domain' in the object list, then close the Object Management Dialog
Set the grid:
Click on the 'Mesh toggle' button. The default mesh (shown as blue and orange lines) will appear on the screen. The orange lines are 'regions', defined by the bounding boxes of the objects.
The default grid of 55 cells in X and 60 in Z is adequate for the tutorial.
Set the remaining solution control parameters:
Change the monitoring point by setting the X,Y and Z positions on the handset to:
Xpos to 3.0,
Ypos to 0.5,
Zpos to 0.75
Click on 'Main Menu' and then on 'Numerics'.
Set the number of iterations to 300 (this is not sufficient for complete convergence, but it gives a reasonable flow field).

To view:
To select the plotting variable:
To change the direction of the plotting plane, set the slice direction to X, Y or Z 
To change the position of the plotting plane, move the probe using the probe position buttons
on the toolbar or double-click the
probe itself to bring up the Probe Location dialog.
A typical plot from this case is:
In the PHOENICS-VR environment, click on 'Save as a case', make a new folder called 'JETPUMP' (e.g.) and save as 'CASE1' (e.g.).
