Error:problem with PART line, water mist model

[Roger]

Hi there,

Roger comes back again. :-) Is everything going well with you guys?
Here comes the question. Yesterday i build up a simple scenario to
test water mist suppression. And i met a problem, see title. I've
tested fire geometry and it's ok, when i tested the last part , part-
prop-nozzle commands, this error message popped up. Then i read
relative part in guide, didn't find relative explanations, and my mind
totally messed up.

--------------------------------------------------------------------------------
PART ID ='MIST',
EVAPORATE ='FALSE',
DENSITY =1010,
SPECIFIC_HEAT =4.2,
HEAT_OF_VAPORIZATION =10000,
MELTING_TEMPERATURE =0,
EVAPORATION_TEMPERATURE=100,
QUANTITIES ='DROPLET DIAMETER',
DIAMETER =50,
MAXIMUM_DIAMETER =75,
INITIAL_TEMPERATURE =20.

PROP ID ='NOZZLE',
QUANTITY ='SPRINKLER LINK TEMPERATURE',
DROPLET_VELOCITY =10,
FLOW_RATE =5.38,
PART_ID ='MIST',
OFFSET =0.06,
SPRAY_ANGLE =0.,26.,
OPERATING_PRESSURE =110

&DEVC ID='NOZZLE1', XYZ=1.8,4.8,3, PROP_ID='NOZZLE',
ORIENTATION=0,0,-1, QUATITY='TIME', SETPOINT=20. / # HP NOZZLE1
&DEVC ID='NOZZLE2', XYZ=1.8,1.8,3, PROP_ID='NOZZLE',
ORIENTATION=0,0,-1, QUATITY='TIME', SETPOINT=20. / # HP NOZZLE2
&DEVC ID='NOZZLE3', XYZ=4.8,1.8,3, PROP_ID='NOZZLE',
ORIENTATION=0,0,-1, QUATITY='TIME', SETPOINT=20. / # HP NOZZLE3
&DEVC ID='NOZZLE4', XYZ=4.8,4.8,3, PROP_ID='NOZZLE',
ORIENTATION=0,0,-1, QUATITY='TIME', SETPOINT=20. / # HP NOZZLE4

Hope you professionals could give me some clues or suggestions, thank
you !

With regards,

Roger

Hm.......these 4 nozzles are 'suspending' beneath ceiling without
touching any surfaces.
Ceiling height is z=3.5m, nozzle height z=3m. Do i need any other
strings besides ORIENTATION designation?

[Roger]

I deleted the Ampersands before PART and PROP and add another string
problem still exist.
Here's the test string:
"&PROP ID='Spr1', QUANTITY='SPRINKLER LINK TEMPERATURE',
FLOW_RATE=28.9, DROPLET_VELOCITY=10.00, PART_ID='water_drops'/
&PART ID='water_drops', WATER=.TRUE.,SAMPLING_FACTOR=1,
QUANTITIES='DROPLET_DIAMETER',DIAMETER=163./ "

The back of the User's Guide contains tables of all parameters. Check
that all your parameters are valid, and that you use the right syntax.
For example, it is not 'FALSE' -- you must write .FALSE. for a logical
parameter. Anytime you see "ERROR: PROBLEM with ... line" it means
that there is a syntax problem.

Dear Kevin,

I read chapter 14 and table of commands, finally didn't find any clue
for my problem.
Totally have no idea about this. :(

The test string in my own second reply works in another case,but not
in this water mist case. I'm so confused about it.

Go to the offending line in your input file. Move the '/' to middle
of the input line. Try and run FDS. If it runs, the error lies on
the second half of the line. If it fails, the error is on the first
half. Repeat until you locate the offending command.
