The compression of gas by a piston-cylinder combination is
simulated by the use of the In-Form BOX function.
The "fluid" within the piston is given a velocity which
corresponds the rotation of the crank.
At a precribed instant a valve provides a fixed-pressurse outlet
in the cylinder wall. This is achieved by use of a boundary
condition embodying the In-Form IF condition.
