Summary0000785: Incorrect introduced mass in sprayFoam / aachenBomb
DescriptionThe mass introduced in the default aachenBomb tutorial is much less than that specified in the constant/sprayCloudProperties. The totalMass of 6mg is never reached and after the injection is complete the mass in the system is just under 2mg.

The fix is to lower the parcelsPerSecond to 2E+06 down from 2E+07.
Steps To ReproduceSimply run the aachenBomb tutorial and monitor the 'mass introduced'.
At the end you may integrate C7H16 (*rho) over the domain (in Paraview) to confirm.
Additional InformationApplies to:
OpenFOAM 2.0, 2.1, 2.2 and their repository versions

This is fixed in 2.2/2.2.x, and it should not be necessary to change the parcelsPerSecond parameter

Version 2.2 yields the following result - not quite 6 mg, but very close...

Solving cloud sprayCloud
Cloud: sprayCloud
    Current number of parcels = 0
    Current mass in system = 0
    Linear momentum = (0 0 0)
   |Linear momentum| = 0
    Linear kinetic energy = 0
    Rotational kinetic energy = 0

        number of parcels added = 12301
        mass introduced = 5.99711e-06
    Parcels absorbed into film = 0
    New film detached parcels = 0
    Parcel fate (number, mass)
      - escape = 0, 0

    Mass transfer phase change = 5.99714e-06
