Dear Sirs,
I have been working with FDS+EVAC only for a short period of time, so probably I will make many mistakes while programming my file. I am trying to simulate the evacuation of a six floor building using stairs with EVSS. It is a simple model but when I try to run it I get an error: Specify orientation of VENT 2, MESH NUMBER 2
My second Mesh is the first one of the evacuations one, but i do not understand what I am supposed to specify, as I do not know if I should write any VENT command line. I am using FDS6 and I have tried to write this file using as example one about stairs I founded on the website, and I think I am doing everything as I see in the other file.
Here I write all the lines:

I have read a lot in this group and in the users guide and I am not able to solve the problem. I would be really pleased if anyone could help me with this exercise.
Thank you very much for your help.

Hello,
I am familiar with ver 5 FDS+EVAC, but I added these 2 lines to your input file:
&SURF ID = 'OUTFLOW', VEL = 0.000001, TAU_V=0.1/
&VENT SURF_ID='OUTFLOW', XB=4,4, 0,0, 0.8,1.2,EVACUATION=.TRUE., MESH_ID='Mesh_0'/
and now get the error:
Specify orientation of VENT 3, MESH NUMBER 2,
so it might be a start to fixing the input.
I also put "/" at the end of your &EVAC line.
good luck!

Thank you very much for your quick answer Brad.
I have tried what you have advised but once I write 8 VENTs lines, one for each evacuation mesh, all I get is a change in the error from ''VENT 2, MESH 2'' to ''VENT 10, MESH 2''. I am still trying to solve the problem and if I were able to solve it I will publish the answer. Meanwhile any kind of help is welcome. Thank you very much again.

You are welcome Fernando. I wish I could solve the problem, and if you were using v5 FDS+EVAC I would have a better chance. I think something v6 does is eliminate the need for additional EVAC VENTS, to make it easier. But I think the extra work required for v5 is worth it because everything functions as I expect. If you are doing EVAC only, I think you would be just a few steps away from having a working model using v5!!

Well, I have been out of the office a couple of weeks, needed to spend all
"last year holidays" until the end of April. Have you already checked the
page: http://www.vtt.fi/proj/fdsevac/fdsevac_documents.jsp?lang=en
and there the "How to debug your input file: Readme_InputErrors.txt",
where the Readme_InputErrors.txt is a link to a text file:
http://virtual.vtt.fi/virtual/proj6/fdsevac/documents/Readme_InputErrors.txt
What to do:
1: comment away the &EVSS lines, e.g., take the "&" away.
2: Check that your have SLCF output for the guiding evacuation flow
fields (at a z-level of your evacuation meshes).
3: Take the agents away (speeds things out), &EVAC lines away (i.e., just
the "&" away).
4: Set T_END=0.1s (or something similar) so that the guiding flow fields
are calculated. And run the case with EVACUATION_DRILL=.TRUE. on
the MISC-namelist.
See things in Smokeview. You could also use COLOR keyword on our
DOOR, ENTR and EXIT lines, so that you can recognize different doors
better in Smokeview. And you could also use COLOR on the vent lines.
Note that a door (or exit) that is a target of (some) agents, should have a
vent defined on it (in FDS 5, in FDS 6 this is automatic). And a vent should
have at least one grid cell thick OBST behind it. Use THICKEN=.TRUE. on
the OBST lines to force this.
A common note for stairs: You should have the stair flights that have
same (x,y) coordinates, but different z-location, in different meshes.
Say, 3 storey building, stair flight SF_A is going up from a floor to an
intermediate landing IML and stair flight SF_B is going up form the
intermediate landing to the upper floor. One way of defining the
different parts of the stairs to different meshes (1st floor, 2nd floor,
and 3rd floor) would be:
1st floor mesh: SF_A_1stfloor, IML_1stfloor, SF_B_1stfloor and here
a DOOR (or ENTR) DoorOut_2ndTo1st. Put also an OBST here (could
be zero thick, no vent for this door, where agents are coming out, the
flow direction is now 3rd floor => 1st floor, i.e., downwards). See also
that the sides of the flights and landings are "closed" so your have
there the OBSTs needed.
Note, that you can not have other agents on the 1st floors that are walking under the
stair flight SF_B_1stfloor. If this could hapen in your geometry, then you
should put the SF_B_1stfloor flight to the second floor mesh (and the
intermediate landing, if needed also). And if you would have similar problems
in the 2nd floor (you floor height is large), then you could overcome this by
making the intermediate landings as their own main evacuation meshes
(and put the stair flights also to these meshes).
2nd floor mesh: DoorIn_2ndTo1st and an outflow vent here also. And an
OBST (at least one grid cell thick) behind the door and vent. SF_A_2ndfloor
and IML_2ndfloor, and SF_B_2ndfloor and a DOOR (or ENTR) DoorOut_3rdTo2nd.
(And same notes apply here than for the 1st floor case.)
3rd floor mesh: DoorIn_3rdTo2nd and an outflow vent here also. And an
OBST (at least one grid cell thick) behind the door and vent.
To get an eight storey stairs should be simple. Just copy-and-paste the 2nd floor
mesh part as many times as needed.
Above is for the FDS 5 based evacuation, the FDS 6 based evacuation is similar,
but should not define the outflow vents (and need not to place the OBSTs that
are needed by the outflow vents). And you should not define the additional
door flow evacuation meshes, just the main evacuation meshes are enough.
FDS 6 evacuation automatically places one grid cell thick OBSTs behind all
EXITs and "outflow" DOORs and puts there also the vents. And uses the main
evacuation mesh to calculate the guiding flow field towards every different
DOOR/EXIT on that mesh, one after the other in the initialization phase and
saves them to the hard drive.

Thank you very much for your deep explanation.
Finally I was able to find my mistake. It was in the position of each of the doors which are connected between them, so it was not possible to for the people to go through them.
