Nice CFD Vector Plot!
 

Dear experts,

I wanted to plot nice Vector plot. However if I I pick sampling via vertex. The vector will be crowded! and some is far apart. Very confusing.

I came across one method known as Equally spaced vector plot but the maximum sampling is 100000. And the color is via constant. The arrow size dictates flow velocity magnitude. Will this adjustment made my flow field 'inaccurate' as Post displays the flow field by equally spacing the arrow.

I am so confused, is there a good guideline for plotting a nice vector that allow seeing rotating flow nicely.

Meanwhile, if I load let says 4 data files together. The post will average the arrow scale and made it even terrible to display vector which means I lost the rotating flow at some point!!

Thanks

Kind Regards,
