Hello everybody,

i want to use VOF to capture the interface of liquid-solid in an open canal. the solid is located in the bottom of the canal and is going to be deformed. the deformation of the solid is something that i can compute with almost analytical ways. But I need this deformation to be 'understood' by the flow through the VOF capturing of the liquid-solid interface.

SO what I want to do is to use VOF to couple the solid deformation with the flow. I know there are other ways to accomplish it, but I am interested in using VOF. The methodologies theat treat the solid as a fluid and solve mixture equations close the interface are not interesting to me. I want to use VOF to capture the boundary and impose the boundary conditions to it.
The flow and the solid are described by different equations. The interface is going to be defined by the solid deformation.

Does anybody have any idea how this could be done?? Any papers that describe similar attempts are most wellcome!!
