Is there an option to draw curved staircase for Pathfinder?

While this is a feature request in our tracking system, it is not currently an option with Pathfinder.
You must build all geometry into a single file.

Because of the large floor size, we are distributing the work among a group. There's one who's doing the ground floor and another person doing the first floor and so. In the end we need to merge these files into one on different levels. Is there a way of doing this on pathfinder?

I am learning FDS and I am with my first model. The data I have is igneo material is a quantity of wood of 500 kg.
What value of HRRpua do I assign to the burner material?
How design fire?
Thank you.

Hello Dear Pathfinders

I saw that Pathfinder can visualize Smoke [and fire] from FDS fire simulations.

I wonder if I could import Smoke [and fire] data for visualisation computed with other tools. At least it should be possible, if I generate the input data in the FDS Smokeview format? Which files should I generate? Only s3d? Or also boundary data?

I do fire simulations with StarCCM+ and can compute for instance smoke concentrations, optical density, extinction coefficients, temperatures, etc.

Thanks and greetings!

Please verify that your graphics hardware drivers are updated.

hello forum, happy new year .
My query is that can we model jet fan flow in inclined position to coordinates, for car park FDS ventilation study ?.

I am trying to model burn away case and from manual I understood that :

1. The thickness of the OBST is not relevant to the 1- D heat transfer calculation and the thickness in the SURF line is used, however for burn away the OBST thickness matters (burn away time was changing in sample cases).

2. Does the thickness of the OBST have to be the actual thickness (in my case it is in mm), and my mesh has to been fine enough to model such a thickness? 

3. Can we keep obstruction thickness smaller than the mesh cell size and still that obstruction will be captured for both heat and flow calculations ?

 4. If an obstruction thickness is smaller than the mesh cell size , will burn_away work in this case?

Please correct me where I am wrong.

I am using burn away option and I noticed that when I am selecting PyroSim geometry in scene geometry then obstruction is going away at 3s while when Actual FDS is selected then the obstruction is going away at 5 s. Why this is happening and which is correct. It must be some error in PyroSIM results viewer. Please explain
