a problem about CFD-post
 
hey,

I have a problem here in post-poccessing.
I do not know how to export velocity contour lines data, say, v=0.2 m/s.
I'd like to compare zones specified by velocity threshold value of different cases, and I can not find a way to export the contour lines of interest (eg. level 2 or 3).

could anyone help me for this ?
I will appreciate it very much. thank u.

Create a user surface based on contour level (level value is your choice).

For the contour objext, I suggest using list values for the contours so that you can control the level of the user surface precisely.

Export the user surface.

Thank you so much for your reply. I'll try in that way.

if you only want the contour line for a level, create a polyline based on the contour level.

thanks "singer1812 & Hwangpo" . It is working

I tried with polyline method but it didn't work anyway because I wanted to export velocities and locations in order to draw some pictures using them.
I will try it again by the way and thank u so much.
