how to export this kind Figure using cfd-post
 

hey guys,

I'd like to draw some figures as the attachment like.
In cfd-post, I do have velocity contour lines on certain horizontal planes of several cases but i don't know how to export the data. I wanna compare the range of influenced zones for different scenarios.

I had utilize 'polyline' or 'user surface' function in cfd-post, and when I was going to generate a chart, there was a problem. I didn't know how to make it.
This kind of fig (say, velocity profile on horizontal plane of z=0) is likely 2.5-D, plotting a line of velocity=certain value (or a contour level) on x-y plane, isn't it?
anyone knows how to do it?
any help would be very appreciated.

those lines in the pic are 'velocity=0.1 m/s' for various simulating cases

Exporting the data is easy - just go file/export and select the base object. It could be the contour lines, it could be polylines, it could be anything. Then use Excel,matlab,python whatever you fancy to draw the graph.
