How can arc-length be x-coordinate of a chart?

shenying0710 · December 28, 2012, 01:42

Hi, my friends,
I want to make a chart to show the pressure distribution along a curve on a blade, but I don't know how to make the arclength-coordinate. It seems that there's no such variable in the list of variable selector.
Thank you.

If you make a line object along a blade surface you should have length along the line as a variable.

Thanks, Glenn. I see a variable named 'length' in the list of the variable selector, but from the final chart, I feel it's not the length along the object line.

I am not sure what is going on there. I would export the data along the line and see if an external package (excel, matlab, whatever) makes sense of it.
