How to plot FTLE having VTM database

[rociocarratalasaez]

Dear VisIt developers,

I successfully installed the software in Linux using the 3.3.1 version for Ubuntu 20.

Now, I am trying to use VisIt to:

1. Compute the flowmap
2. Compute the FTLE
3. Plot the result

Of a VTM database I have, representing a 2D Porous Blockage - like scenario, which simply has a blockage close to the left side of the geometry, as it can be seen in the following picture.

As it can be seen in the picture, I have been able to show the contour, so the VTM database has been properly read.

My question is: from that, how can I compute the flowmap, FTLE and finally plot the result?

Thanks so much!

Hi Rocío,

Those are all part of the "Integral Curve System". Here is the link to the overview of it.

For your specific questions, you can find more information about the flowmap at
