Hi!
Why do I get an error message when I click on the 'Export to IDL' tab ? I am trying to find a way to import the vapor field lines into idl for further analysis..
Thanks,
Lily
I'm not sure why you are getting that message, but "export to IDL" won't do what you want. You can export the advection points along the field line by using the "Save Flow" button on the Flow tab. The tricky thing is figuring out the output format. If you have 10 stream lines you'll get
10 * n lines of output, where n is the number of advection points for each field line. So the first n lines will be the advection points for line #1, the second n lines will be the points for line #2, and so on.
Thanks for the quick reply John!
Could the format of the output be version dependent? I tried the "Save Flow" button for various numbers of seed counts I get a file with 4 columns (like the 4 columns of x,y,z,timestep of the file you get when you hit the "Save Seeds" button). When I open the file, all 3 first columns always have the number 1e+30 and the 4th column has 0.

A value of 1e+30 indicates that the point is outside the domain bounds. If you are seeing stream lines at least some of the values should reside within the domain. There may be lots of 1e+30 values if the streamlines exit the domain quickly.
