I am not clear how the membrane is modeled (sorry, I havenot seen any paper about this), so I would like to state my consideration more clear and you can get my meaning. What I am considerring of the fluid boundary(static fluid pressure) is that there is a fluid boundary that the fluid pressure (it is external fluid pressure force) is applied on the boundary. but I do not know how to model it, and how to get the boundary force form the fluid. Because under the Pressure from other sides, the shape of the boundary touching the fluid is changing, and the particles distribution around the fluided boundary is also changing, so how to get the force on each particle touching the fluid from the fluid. Also, the particle may be seperated from the solid part and flow in the fluid under the simulation, then how to find the new boundary touching the fluid, it is also a challenge. Kan >Bruno
