Question Visualise liquid film

Hello,
I started working with openFOAM/Paraview recently and have to simulate some droplets hitting a surface.

So I wanted to do the tutorial with the 'hot boxes':
http://openfoam.org/release/2-0-0/surface-film/

I think I should get a result comparable to the one in the link. But I just manage to display the waterdroplets. Not the liquid film on the box/floor.
What options/data do I have to display to get the result like in the picture?

Thanks for your help!

Found the solution at: http://www.tfd.chalmers.se/~hani/kur...oam_report.pdf

foamToVTK -noZero
foamToVTK -noZero -region wallFilmRegion


'All VTK les resides in the VTK/folder; themost interesting ones are probably evaporatingSpray_..vtk (fuid data), lagrangian/reactingCloud1/reactingCloud1_..vtk (spray data) andwallFilmRegion/region0_to_wallFilmRegion_wallFilmFaces/region0_to_wallFilmRegion_wallFilmFaces_..vtk(wall lm data).'

Hello foamers. I am working on sprayFoam and I have started working on surface film modeling and droplet impingement interaction with the film.
Please tell me what I have to do (what options/data/filters I have to apply) in order to visualise the surface film thickness as shown in figure 4. b. (the right hand side figure) of the image that I have attached below in paraview.
I have converted the film region to VTK and uploaded in paraview. But from that I only get a contour visualisation of the film thickness. What extra filters/data I have to apply to get the physical visualisation of the film as given in the figure.

Hi, I'am working on a similar problem and did exactly as the link you posted suggests, but the only data that I managed to show is phi, and I would really like to show velocity too. When I reconstruct the wall film region (since I am decomposing the problem for parallel running) I get this:

Skipping time 0.18

Skipping time 0.19

Skipping time 0.2


End




Any Idea how to solve this?
