I will redirect my question here so that Timo or Gregor or anyone else can discuss or answer the question. I ask this question for long-term solution as Randy expected. The question is related to FDS Issue #8386, but not limited to that issue.
In divg.f90 Timo wrote as below
! Evacuation flow field calculation: Change the outflow vent pressure zone and initialize everything
! New exit/door flow field calculation (new outflow-vent), do the necessary initializaions,
! because same arrays are used for exits/doors at a main evacuation mesh. Each evacuation
! flow field calculation has just one exit/door, i.e., outflow vent, so the pressure zone
! is defined so that the front of the door is in the pressure zone. So, pressure zone
! is also redefined for this main evacuation mesh.
! One pressure zone is defined for each main evacuation mesh.
In brief my question is why the evac pressure zones are defined in fds6 and how they affact evacuation flow field. If I understand Timo's algorithm correctly, such pressure zones are not defined in fds5. If Randy expects that evac runs after fds as a long-term solution and Timo has supported this solution, the evacuation flow field is a critical issue to deal with in Timo's algorithm.
