PyroSim / HRR curve definition
« on: September 27, 2014, 10:05:54 pm »
Excuse me,

I want to define the HRR curve like I show in the figure, but i don't know how can I do it in Pyrosim.  :(
I know that i must define the HRRPUA, and I select rump-up time: t^2, and define a time, but, What is the meaning of this time? How know I Which is the duration that the program considered to the constant part? When is it start?.

Thanks.

PyroSim / Check the results
« on: August 22, 2014, 08:10:52 pm »
Hello.. Excuse me

How can I check the results of my model? Are there typical curves to check my results obtained in a building?  ???
What is the typical temperature acquired on walls during a fire?
Is it normal increase and decrease temperature on walls during a fire? What cause this effect?.  :-\

(The model is about an academic building)

Any comment will be useful. Thanks!  :D

PyroSim / Size Grid ..
« on: July 26, 2014, 08:55:47 pm »
Hello,

I made a model in pyrosim of an academic building, but i don't know How set the grid dimensions compared to the size of the building, to represent a real situation.   ???

My idea is represent as the smoke out of the building through open doors and windows. I thought that this was posible to making the grid bigger than the building.

So, What size i make my grid? or is there a simpler way?  ???

Any recommendations will be useful.  ;)

Thanks!

PyroSim / HRR curve and Fuel Load
« on: June 25, 2014, 01:28:22 pm »
Hello, :D

I made a model in pyrosim of an academic building (class, offices, meeting rooms).
I can calculate the entire fuel load per room (MJ), How can I relate the fuel load to the HRR max (FDS input)?, or is it possible define the fuel load direct?. ???

Any recommendation for how modeling the fire in this building will be welcome.

Thanks.   ;)

PyroSim / Smokeview options.
« on: June 22, 2014, 09:59:40 pm »
Hello  :),

I made a model of a three levels building (just a one mesh), then i would like to see the spread of smoke, and other properties, ┬┐Can I create cuts to see the spread of smoke (e.g) per plant?

Thanks a lot.

Regards!
