IncidentSelector
- IncidentSelector:
- Determines how random incidents are selected. The IncidentSelector block is defined at the top level of the MonteCarloInteractions block. 
IncidentSelector Parameters
Presently, the IncidentSelector can be of two different kinds:
- nullOnlySelector:
- Works with VSimPD and VSimPA licenses. - To be used if the MonteCarloInteractions` block contains only Null Interaction blocks, each interaction is performed consecutively at each time step. If any Interaction blocks are present, they are ignored. 
- unbiasedSelector
- Works with VSimPD and VSimPA licenses. - Selects incidents in an unbiased manner according to their probability only. This selector allows each macroparticle to interact only once per time step.
