set zone in interDyMFoam (OF1.5-dev). how to?
 

Hello,
I'm using a slightly modified version of interDyMFoam in OpenFoam1.5-dev for a test case (floating barge). I'm interested in keeping the mesh near the barge as rigid as possible.
I was thinking of making a set zone, but I don't know how to do it. Can anyone help me?
does anyone have other suggesions? I also thought of writing a new diffusivity type, but I'm afraid it is a bit more complicated...


thanks,
Davide
