Description
Pressure boundary condition obtained from a 0-D model of the cylinder
of a syringe.  The syringe cylinder is defined by it's initial volume,
piston area and velocity profile specified by regions of constant
acceleration, speed and deceleration.  The gas in the cylinder is
described by it's initial pressure and compressibility which is
assumed constant, i.e. isothermal expansion/compression.

Example of the BC specification:

outlet
{
    type            syringePressure;
    Ap              1.388e-6; // syringe piston area
    Sp              0.01;     // syringe piston speed
    VsI             1.388e-8; // Initial syringe volume
    tas             0.001;    // Start of piston acceleration
    tae             0.002;    // End of piston acceleration
    tds             0.005;    // Start of piston deceleration
    tde             0.006;    // end of piston deceleration
    psI             1e5;      // Initial syringe pressure
    psi             1e-5;     // Gas compressibility
    ams             0;        // Added (or removed) gas mass 
                              // Initially 0 but used for restarting.
