strange curvature with interFoam (comparison with Brackbill work)

Hi again Duong,

i would like to test your filter (the one in the Ubbink's thesys). Did you put the smoother inside the simulation or you use it to calculate the curvature as a postprocessing?

Thanks
Andrea

I implemented in OF.

Cheers

Hi Duong,

I do not know if I am able to implement this calculation. I am relative new in OF and c++. maybe if you want to share your code.
I read the Ubbink's thesys and it seems he can find good results with that filter.

here my e-mail: ndr.ferrari@gmail.com

thanks

Hi,
I am trying to model a droplet on an oscillating surface. For the surface I am using dynamicInkJetFvMesh and interDyMFoam solver.

As a base case, I started with a droplet on fixed surface and with interFoam solver. However droplet slips off the surface after some time. BC that I gave at the surface are the zero gradient for alpha and P_rgh and fixedValue for U, rest of all sides are atmosphere. Can anybody tell me if I need to incorporate some kind of friction between drop and surface or no-slip condition betwn them ? And if so then how can that be implemented.

Sry for posting here in this thread, but its seems kind of related to the same solver and same curvature problem.. hope for some reply..

Regards
