What do you mean by 'membrane'? If you refer e.g. to the damBreak tutorial, there is no real membrane or something. The water column at t=0 is just set in the setFields dict as an initial condition.

These are the some of the lines from dam break tutorial " The test setup consists of a column of water at rest located behind a membrane on the left side of a tank. At time , the membrane is removed and the column of water collapses"

The membrane which holds the water column at rest at t=0?

That would be the experimental set up, as Arne says in the damBreak tutorial water is located with setFields (setFieldsDict) which fills the cells located within a box with no more constraints. At time t=0 your water is at rest in the given zone, so you could think that in time 0-dt there was a membrane and now it is there no more, but there is actually nothing there.
