Zone 49 meets zone 0 error

[lemste...@gmail.com]

Hi all,

I am trying to run a simulation of an open stadium, no HVAC, no pressure zones, but getting an error:

ERROR: ZONE 49 meets ZONE  0 at the boundary of MESH   22 and MESH   21

ERROR: ZONE 49 meets ZONE  0 at the boundary of MESH   22 and MESH   21

ERROR: ZONE 49 meets ZONE  0 at the boundary of MESH   22 and MESH   21

Unfortunately can't attach my fds file. How can I solve this?

Thank you in advance

FDS now automatically identifies sealed regions in your domain. Somewhere along the interface between meshes 21 and 22 is the 49th such sealed volume that FDS located.  This may be related to this thread: https://groups.google.com/g/fds-smv/c/eDgUzYKucFY/m/HBEGGP-6AwAJ 

I suggest you look carefully at your geometry in Smokeview and find and fill in voids between the meshes.
