Hi Szymon, I think that the arrow heads are being drawn but are too small. The algorithm makes a choice on the length scale for the vectors and that includes the size of the arrow heads, but for this case the default scale isn't a good one. In your example, the length scale that's used is 20. Try your curvilinear plot with a smaller value, say VECTOR/LENGTH=10, or VECTOR/LENGTH=5 I've attached an example I tried, where the plot that used a setting of /LENGTH=1 had very small arrow heads, and /LENGTH=0.5 draws larger ones.

Hi there, It's an odd issue when I draw vectors (wind data) on curvilinear grid the arrow-heads are missing. Everything is correct when I draw in rectilinear coordinates. I attach files. -- Best regards, Szymon Roziewski
