STAR-CCM+ provides a number of predefined views which allow scenes to be displayed relative to common orientations of the xyz axes. These are useful when you wish to orientate the scene with an axis or when the orientation of the scene has become difficult to determine and you wish to reset the scene relative to an axis.
From the Scene toolbar, click on the camera icon and select Look Down from the drop down menu. This reveals another drop-down menu from which you must choose the axis to look down. For instance, if the +X axis is selected the resulting view will have you looking along the x-axis with positive x pointing out of the screen. If you choose the -X axis the resulting view will have you looking along the x-axis with negative x pointing out of the screen. Once an axis and direction has been chosen you must then select a second axis and direction from the drop-down menu which will define the view up.
An additional option to view the scene along the vector [1,1,1] is also provided.
