PyroSim / Attach a vent to a wall
« on: September 05, 2011, 04:38:22 am »
Hi everyone,

After summer vacation I'm coming with a new question : I have to attach vent to walls, but I've always the same error : "VENT XX must be attached to soli obstruction".

I don't know how to attach correctly vents to walls. Can you help me?  ???

PyroSim / Complicated roof
« on: July 19, 2011, 06:34:20 am »
Hi everyone,

Again a question coming from me! Suppose you are used to  ;D

I have to build up a complexe roof and I don't know how to do it. I tried with the "triangle" tool but I find it very complicated.

How would you do that?

PyroSim / Soot yield and heat of combustion
« on: May 18, 2011, 05:06:06 am »
Hi everyone,

Here in Switzerland the government tells us that for all cases calculated by FDS we have to put a soot yield of 0.04 and a heat of combustion of 25 kJ/g.
I find that these entries are very big. Am I right?  ???

Where can I find the heat of combustion and soot yield for an office fire?

Thanks a lot, your work is amazing!

PyroSim / Problem with burner
« on: May 05, 2011, 06:37:00 am »
Hi there,
I have a really big problem with Pyrosim.
I created a model from a building with a burner inside it. Until today, the model was perfectly running.
But today, when I just wanted to move the burner to put it in another place, the burner is not more working!
And worse, I created the same model with the same burner, and it is alos not working. I don't really understand what is going on. Suddenly the burner doesn't work any more.
Could you please just help me? I'm totally lost...

PyroSim / Modify scale on Pyrosim and soot yield
« on: March 21, 2011, 04:33:38 am »
Hi everyone,
I'm coming again with questions!

I have two problems with my calculations :

- The first is with the scale on the smokeview view. For example, the scale shows me the maximum soot contentration that I have in my room : 100 mg/m3. My client wants me to change the scale to prove that there is nothing at 120 mg/m3. How can I do that?

- The second thing is the soot yield. I've defined a burner without reaction, and the client wants to know the soot yield. Where can I find it (and change it?).

Thanks a lot,
Laure from Switzerland

PyroSim / Problem with open vent
« on: February 15, 2011, 08:12:35 am »
Hi everyone,
I''ve a problem in setting an open vent at the top of a room (to allow the smoke to go out).
When I set the vent (Open surface), the smoke is not going out.
I suppose I''ve a problem with the mesh boundaries but I don''t really understand what to do.
I''ve just set a normal mesh.

What do I have to do? Thanks a lot!!

PyroSim / Exhaust proble,
« on: December 06, 2010, 04:38:09 am »
Hello,
I''''m new on the forum. I''''m from Switzerland and working on fire modelling for my job.

I''ve a problem. I''ve made a simulation with an exhaust surface at the top of the room.
I think there''s a problem because where I run the simulation I can''t see the smoke going through the exhaust surface.

Ho do you build exhaust surfaces?

Thanks a lot,
Laure
