I want to ask about how to draw streamlines in the plot section. Because when I click the bottom "draw streamlines", a cross appears but then I don't know what to do with it (like the figure attached). May you help me solve this problem?
Hi, usually, you would just click you left mouse button to start a streamline... But maybe they won't be displayed, because there is hardly any stream that a line could follow? Is there anything displayed in the command window?
