Usually, when performing a particular simulation, it is necessary to compare the results of similar models or the same model at different operating conditions. It is important that the two (or more) cases being compared be viewed from the same angle and at the same zoom level. In other words, the cases need to have the same viewpoint or camera setting. This can easily be done with the ‘Copy Viewpoint’ and ‘Past Viewpoint’ tools. The example shown below illustrates the use of these tools.

Figure 1.  Models loaded in different viewers.  Desired model orientation attained in the left viewer

Once the models have been imported into different viewers in CFD-VIEW, they can be tiled vertically or horizontally if the models are to be visualized side-by-side. One of the models can then be rotated, panned and zoomed to get it in the desired orientation.

Figure 2.  Copy/Paste Viewpoint options

Click anywhere on the viewer with the properly oriented model (to make it the active viewer) and select View → Copy Viewpoint. Then click on the second viewer and select View → Paste Viewpoint. The second viewer orients the model in the same way as the first.

same orientation. Iso-surfaces and particle traces shown

The  'Copy Viewpoint’ and ‘Past Viewpoint’ tools are available under the View menu in CFD-GEOM, CFD-VIEW, and CFD-VisCART.
