In a relevant tutorial, when rotating the stream lines tool, an indication of the degrees value is seen on the screen. Nevertheless, when I applicate stream lines, this indication does not appear. How can I turn it on, so that I can see how many degrees is the tool being rotated?

Hello So-Ine The degree option appears when you are rotating the cut-plane.

To what does the "Delta T" selection refer?

So-Ine Can you provide more details on "Delta T" selection that you are referring? Maybe a snapshot where you are seeing this option.

Hello So-Ine  

Delta T or Step Size sets the size of the time steps used in the display. The number of steps is fixed but you can control the length of time for each step. You change Step Size using a slider. 

If you set a small Step Size, you can view the Streamlines early in the flow.

Smaller time steps allow you to capture more detail. As you increase the time step, faster particles will travel farther than slower particles so Streamlines will terminate in different locations along the direction of flow depending on their velocity.

Please check out the help document for detailed information through images on this option.
