Closing valve implementation

Hey guys,
Some weeks ago I came up with a problem that was solved in this thread (basically by Mr Gschaider): How to change a boundary condition depending on a probe set http://www.cfd-online.com/Forums/ope...ng-valves.html and a final(very simple) test case http://www.cfd-online.com/Forums/ope...ed-up-bcs.html In the meantime my work changed a bit: What I need to do is closing a valve depending on the filling level of a tank. I think I have to implement a solution-based dynamic mesh. Is there any tutorial for this (only found tutorials with a mesh motion that didnt depend on the solution)? If you see the attached picture you can see a slice through my valve: It is a self floating device that will close the ventilation pipe above it. Is there any way that I can move the valve (single stl) depending on the fluid level? In my dreams I would like to define a translation in z-direction depending on the alpha value of a probe set that is aligned in the centre axis of the valve in z-direction. Any suggestions? Any help? I never used a dynamic mesh and couldnt find a "master-dynamic-mesh-dictionary" with all the options (saw something like this once for sampled surfaces). Every help is highly appreciated! Big thanks and greetings, Simon |
