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 NOTIPS = ON |

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. |
