Hi,

I am following the tutorial at [https://youtu.be/HRqHP\_J9uzM](https://youtu.be/HRqHP_J9uzM) which is the OpenFOAM backward facing step example.

I have run the simulation and am trying to generate the Surface LIC view (at 26 minutes into video) but I cannot get the view to work using ParaView 6.0.0.

I suspect the issue is that the SurfaceLIC Integrator dropdown selector box for the Vectors option is empty.

This is my first run at OpenFOAM and ParaView so I am sure I have missed obvious (but not obvious to me).

Thanks in advance
