Hi Jerry, check under the insert menu. You can do cutplots, no flow trajectories. But if you really want to look at flow trajectories, there is no harm in stopping the solution, looking at them and then restarting it where you left off. All these topics are covered in the first couple tutorials and in the flow simulation class. If you're just going through the tutorials, I recommend going through them from the beginning rather than cherry picking tutorials because they build on top of each other.
heres is the info from the help on preview
During the calculation run, you can see the current results in a selected plane.
You can create as many previews as you want. If you want to use planes, which are different from the Global Coordinate System planes, you have to create these planes before the calculation starts because you cannot modify the model while the solver is running.
To create a preview:
- Click Insert Preview on the Monitor toolbar or Insert > Preview: the Preview Settings dialog box appears.
In the Preview Settings dialog box, specify the parameters as needed. See Creating and Editing Preview.
You can also create a new preview by copying an existing preview. Right-click in the preview window and select Clone, if you want to create a copy of the current preview.
To edit a preview:
- Right-click in the preview window and select Properties: the Preview Settings dialog box appears.
In the Preview Settings dialog box change the parameters as needed. See Creating and Editing Preview.
To save the current preview:
Right-click in the preview window and select Save to File. Browse to the folder where you want to save the image, type the desired file name and click Save. The image is saved as a standard .bmp file (256 colors).
You can also specify an auto save mode for a preview. See Preview Options.
I have been struggling with basic fluid dynamics theory. The answer solved the problem. Sorry for my late reply!
