Hi Craig,<br>
<br>
I can confirm that your node ordering is correct. However, the order
of vx, vy is not reversed. You are probably using x for longitude
and y for latitude. In CitcomS, x is the colatitude, y is the
longitude, and z is the radius. This definition will give a
right-handed coordinate system.<br>
<br>
The CitcomS manual is unclear on the definition of x and y
directions. I will update the manual.<br>
<br>
Cheers,<br>
Eh<br>

<div>Here the first loop is the colat, nested in that is the

<div>SO, to read the bvel file, we are essentially reading the
vx,vy corresponding to the points:</div>
<div>colat1 long1</div>
<div>colat1 long2</div>
<div>colat1 long3</div>
<div>...</div>
<div>colat2 long1</div>
<div>colat2 long2</div>
<div>...</div>
<div>etc.</div>
<div>Just wanted to check this, as the velocity format is kind-of
reversed (vx, then vy). Writing a script to convert gplates gpml
to regional citcom input, so if anyone can give me a quick
confirm that'd be great.</div>
<div>Many thanks</div>
