Coupling OpenFOAM and LIGGGHTS

Submitted by en9apr on Wed, 05/17/2017 - 12:05

Hi,

I wondered if there exists a way of coupling a solid model created in OpenFOAM, which solves the wave equation to a DEM model created in LIGGGHTS? The physical situation is a pipe filled with powder and the solid pipe is vibrated to fluidize the powder. The particle phase is dry (no effect of interstitial fluid) but the powder is affected by the vibrations of the solid model through the motion of the boundary, which changes throughout the solid part and depends on the frequency of vibration.

Kind regards,

Andrew

Hi Andrew,

what would you need OpenFOAM for? As far as aI understood your problem all you need is a moving geometry in LIGGGHTS. I'm not quite sure if there is a function for oscillating geometry but I suppose there is.
However if you want to couple LIGGGHTS and OpenFoam as a CFD-DEM coupling, there is a software called CFDEM coupling ;)

Hope I could help you.
