Detailed Description

Pressure boundary condition obtained from a 0-D model of the cylinder of a syringe.

The syringe cylinder is defined by its initial volume, piston area and velocity profile specified by regions of constant acceleration, speed and deceleration. The gas in the cylinder is described by its initial pressure and compressibility which is assumed constant, i.e. isothermal expansion/compression.

Example of the BC specification:

outlet
{
typesyringePressure;
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.
}
