Streamlines on a Surface

[vcoralic]

Hi,

I am wondering whether it is possible to plot streamlines (or LIC, though I get the impression that's not implemented) on a boundary/surface? I've done this in the past in ParaView, by creating a skin friction coefficient vector, and using it to propagate the streamlines/plot LIC. Is there similar functionality in VisIt?

Thanks!

@vcoralic We don't have a way to limit streamlines to a surface and we no longer have LIC-like capability.

For this case, it sounds like it may be useful to seed streamlines using a meshed surface instead of one of the implicit seed functions we provide.

We also do support FTLE, which can give you an idea of streamline divergence.

Thanks for letting me know @cyrush!

By any chance, is there an example you can point me to w.r.t seeding a meshed surface? I tried to play around with it a bit, but couldn't get anything decent (I am sure I was simply doing something incorrectly).

Any insight on what motivated dropping the LIC-like capability?
