Simulation starts when membrane is removed. Visualization of density front evolving through domain. Isovolume of density at value 1.02. A single slice plane also cuts the domain.
Dotted lines represent boundaries of boxes used to represent the domain.
Different view of same simulation. Similar calculation with internal void replaced by a cylinder. Internal surface simulated with embedded boundary techniques. Boundaries of domain boxes are not shown. Similar calculation with larger offsets in the domain.
