Error 562

[Joe-Fitzy]

Hi all,

I've been using 6.8.0 for a while but recently moved to 6.9.1 . Suddenly all my code is popping up with error 562.

IF (DN%NETWORK_ID=='LEAK') THEN
IF (MESHES(NM)%VENTS(NV)%SURF_INDEX == HVAC_SURF_INDEX) THEN
WRITE(MESSAGE,'(3A)') 'ERROR(562): VENT ID:',TRIM(MESHES(NM)%VENTS(NV)%ID),&
' used for localized leakage has SURF_ID HVAC'
CALL SHUTDOWN(MESSAGE,PROCESS_0_ONLY=.FALSE.)

I'm unsure how to fix this, am i modeling leakage wrong? I am currently using leak to ambient on HVAC surfaces. Code available upon request

The Vent ID:

&VENT ID='Lift Leakage 01', SURF_ID='HVAC', XB=6.1,6.1,11.6,12.6,5.2,7.5/
&VENT ID='Lobby Leakage 01', SURF_ID='HVAC', XB=4.7,5.9,9.0,9.0,5.2,5.4/
&VENT ID='Lobby Leakage 02', SURF_ID='HVAC', XB=6.7,6.7,14.2,15.2,5.2,5.4/
&VENT ID='Lobby Leakage 03', SURF_ID='HVAC', XB=4.5,4.5,18.1,19.1,5.2,5.4/

The HVAC Code:

&HVAC ID='Lift Leakage 01', TYPE_ID='LEAK', VENT_ID='Lift Leakage 01', VENT2_ID='AMBIENT', AREA=0.6, LEAK_ENTHALPY=.TRUE./
&HVAC ID='Lobby Leakage 01', TYPE_ID='LEAK', VENT_ID='Lobby Leakage 01', VENT2_ID='AMBIENT', AREA=0.048, LEAK_ENTHALPY=.TRUE./
&HVAC ID='Lobby Leakage 02', TYPE_ID='LEAK', VENT_ID='Lobby Leakage 02', VENT2_ID='AMBIENT', AREA=0.042, LEAK_ENTHALPY=.TRUE./
&HVAC ID='Lobby Leakage 03', TYPE_ID='LEAK', VENT_ID='Lobby Leakage 03', VENT2_ID='AMBIENT', AREA=0.042, LEAK_ENTHALPY=.TRUE./

I have not seen the code but my first guess; are the leak VENTs attached on appearing/disappearing OBSTructions?

@Joe-Fitzy Can you share your FDS input file?

[mcgratta]

In the FDS User's Guide, there is a section called "Error Codes". Look for 562 and it will take you to the section that discusses localized leakage.

Hi all,

Worked it out. The surface couldnt be HVAC when assigned to a HVAC rule.

Many thanks
