I think it works great.

I have created many FDS models that I want to compute with pyrosim, but manual operations are not very convenient. I want to use "BAT" to write a program to execute them continuously. I don't know if you have any experience in this area. Thank you.

Please see section "12.5 Special Flow Pro?les" in the FDS User Guide.

Have you tried running this simulation in the latest version of PyroSim?

How is the smoke supposed to leave the mesh?

Can you attach the DWG file for testing?

Thank you!  I will try that.

And thanks, next time I'll post the PyroSim file.

On our forum, it is usually best to post your PyroSim file, as details can be lost in the conversion to FDS input.
On the FDS-SMV Discussion Group, they prefer FDS input files.

From what I see in your file, you don't have vents connected to the top or bottom of your Fans and the endpoints are set to 'Ambient'.
Vents are how the HVAC network connects to the FDS CFD simulation, they provide an interface between the flow simulation and what happens inside the HVAC submodel.

Since the current version of FDS requires all surfaces to align to an axis, you must figure out a way to represent the vent in this way.

Some Ideas:
- Stair-step the vent, breaking it down into multiple sections (vents) that are controlled together and follow the slope of the roof line.
- Recess a horizontal vent into a cutout in the roof. Where the horizontal vent lies in the midpoint of where the sloped vent would be.

I am sure people could come up with other ideas, but these two come to my mind first.
