Hi,

I try to use OpenFOAM to simulate the dynamic of a film on a solid surface. I need to patch a film on the surface (with a specific thickness). I know how to use the setFieldsDict to initialize the alpha value (liquid) in box (boxToCell) or a sphere (SphereToCell). Unfortunalty the surface that I need to use is not plane (it is a curved shape), so I can't use boxToCell. Anybody know how to set the alpha value near a curved surface (is a parabolic shape)? The optimum is to create a film, attached to this curved surface, with a desired thickness t.

Thanks for your help

Fabio

Fabio,

You could have a look on the solver reactingParcelFilmFoam and its tutorials.
I don't know which solver you are using but with this one you can solve a wall film, coupled or not with lagrangian.
In the initialization, you can define a patch dependant film defined by its thickness and its velocity (in the tangential direction only).

I hope this will be helpful, best regards,

Cedric

Thanks a lot Cetric,

I would like to use my solver, but I will take a look on reactingParcelFilmFoam, and I'll try it.

anyway, someone know how to set an alpha value near a face that it is not planar. I know that exists "surfaceToCell", but I did't understand how to use that.

anybody know how to use surfaceToCell?

Thanks

Fabio
