Design and Settings of AirFlowNetwork model in E+ for large space served by multiple AHUs

I am attempting to model an AirFlowNetwork in E+ as presented in my previous question: Interzone airflow between adjacent zones with open walls and dedicated AHUs, and I have some doubts I would like your help to clear out, which are:

  • What is the difference between MultizoneWithDistribution and MultizoneWithoutDistribution, which are two types of the AirflowNetwork Control that is under Class AirflowNetwork:SimulationControl? For the large space served by multiple AHUs (and I have divided this space into smaller ones with open walls (i.e., open doors) and I want to simulate the airflow network, which option should I use?

  • Can I use AirflowNetwork:MultiZone:SurfaceCrack instead of AirflowNetwork:MultiZone:Component:SimpleOpening/DetailedOpening for my vertical openings, namely the artificial doors and windows I created in the process of dividing this large space I am working on? That is, those doors and windows are not meant to ever close or be operated.

  • Any advices on setting AirflowNetwork:MultiZone:ReferenceCrackConditions?

Thank you.
