Hello everyone,

I was simulating a tunnel with train being the fire source. It will have a nozzle and jet fans assigned with flow rates. At one end of tunnel, there is one station. Due to operation of these jet fans and nozzle, there will be suction at station side, which sucks air from station side. I want to simulate this in Pyrosim/FDS. This has been tried and simulated in other CFD tool (for velocity).

As I have read and tried, there is ONLY option for assigning only dynamic pressure (default 0 Pa) to an OPEN boundary in FDS and PYROSIM.

I wanted to know whether anywhere I can input total pressure.

Or anybody can help me solve for total pressure by knowing dynamic pressure with any co relation/s, that will be of great help.

Any help on this regard would be of great help.

Thanks and Regards,
Bharadwaj
