  DISPLAY
  This example considers a two-stroke engine with loop scavenging.
  It is an unsteady three-dimensional flow with mixing of hot and
  cold streams and with time-varying domain boundaries.
  The exhaust and intake processes take place through ports
  in the lower part of the cylinder wall which are
  progressively uncovered by the descending piston. The
  exhaust port opens first and the cylinder pressure falls
  due to both outflow and cylinder volume change. The inlet
  cylinder pressure has fallen below the total pressure in the
  inlet port. The incoming cold gas displaces and partially
  mixes with the hot exhaust gas.
  The inlet port flow direction makes an angle of 30 deg. to both
  the radial and horizontal directions.
  A single expanding grid is used in the z-direction so that
  the cells representing the ports both expand and are uncovered.
  The patches representing the port cells are active over a range
  of time steps.
