Detailed Description

This boundary condition provides a pressure condition, obtained from a zero-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.

Usage

Property	Description	Required
`Ap`	syringe piston area [m2]	yes
`Sp`	syringe piston speed [m/s]	yes
`VsI`	initial syringe volume [m3]	yes
`tas`	start of piston acceleration [s]	yes
`tae`	end of piston acceleration [s]	yes
`tds`	start of piston deceleration [s]	yes
`tde`	end of piston deceleration [s]	yes
`psI`	initial syringe pressure [Pa]	yes
`psi`	gas compressibility [m2/s2]	yes
`ams`	added (or removed) gas mass [kg]	yes

Example of the BC specification:

    <patchName>
    {
        type            syringePressure;
        Ap              1.388e-6;
        Sp              0.01;
        VsI             1.388e-8;

        tae             0.002;
