pathline jumping
 

Hi!

when I display pathlines, it happend, that some lines are "jumping".

For a while, the line is straight and follows the (straight) flow. But at a point (without obvious reason) the line jumpes to another position, right beside its former position. After that, it keeps on following the flow as it is supposed to... (the shape of the pathline is like a Z).

What happend?? Is it because of the grid size at this position?

Any Idea?
