DISPLAY
High-pressure air is separated from low-pressure air by a
spherical diaphragm concentric with a spherical outer vessel.

The diaphragm suddenly breaks.

The subsequent motion is predicted by a one-dimensional analysis.

The spherical geometry is simulated by the use of VPOR and NPOR,
which are made proportional to iy by the setting iporib=3.
