Hi,
I have been wondering lately whether it is possible to simulate with ALE and Laminar Flow interfaces the motion of an oject in a fluid.
Let us suppose that we have a closed system, i.e. a domain which does not exchange mass with the outside, and there is an object inside such domain. Is it possible to move the object around and see how the fluid redistributes itself?
I have prepared a simple model and I can force the mesh deform with no problem but the velocity of the fluid, water, remains just zero everywhere.
In the ALE interface, I define a free deforming mesh and I impose the proper laws of motion on the boundary of the moving object. By selecting the proper type of smoothing method and order I can even avoid inverted elements.
In the Laminar Flow interface I must define no slip conditions everywhere otherwise if I define moving walls I don't stand a chance to get a solution.
Does any one have an idea which additional boundary conditions /forces / whatever are required?
Cheers
