      In principle, IAC applies to all kinds of dispersed flows. This includes droplets in gas droplets in liquid and bubbles in liquid. However the kernels used for break-up and coalescence are only valid for air bubbles in water. To model breakup and coalescence correctly, it is necessary to implement applicable kernels with a UDF DEFINE_PROPERTY is used to modify and implement the IAC kernels.
