I try to use flexpde5 to draw a flow. I find that the vector() command can only form a vector field. However I want a continuous flow line, which is represented by continuous solid curve, not short arrows, because it is hard to see a lot of arrows in a small picture. Does anybody encounter the same problem? What is your solution, please? Thank you. Thank you very much.

you could remove the arrow tips to make the plot clearer... but there may still be gaps between the lines

Thank you very much.
May I ask one more question? If I cannot draw a continuous line, can I draw the flow line sparser? I think the dashed lines are too denser to be identify.

You could also export to an external visualization tool. FlexPDE allows you to export to either VisiIT or to Tecplot. I've tried both. VisIT is free at http://www.llnl.gov/visit/home.html . It's a bit clunky, but it works. I paid $1,615 for Tecplot a year ago. As you might expect, It's a lot slicker and, in my opinion made better looking plots. Please keep in mind, however, that my application was elastic deformation. So, I did not explore the flow visualization features. VisIT may perform quite well for what you're doing. Both packages appear to be designed primarily for flow problems.
