Hi

See attached screenshot, the airflows remain high. The problem is not in the rollback area, as you can see the airflows in there have gone back to cero but outside there the values remain high any idea why.

Hi Martin

I have uploaded a few screenshots to show the air flow changes: before building the rollback, after building the rollback, after the fire simulation, and after fire simulation and have run the air simulation.

Hope it helps

Regards

Martin

Thanks Martin.

I tried that and it worked but the airflow got all mess up. After doing the simulation it seems like Ventsim can't recalculate properly the airflow and allocates big airflows to the area of the rollback, even after clearing the roll back.

Hi 

Any way I can simulate a fire in a dead end road? No forced air into it.

Hi

Could you share information about the attenuation equation for the overpressure simulation, please?

I am trying to understand how Ventsim calculates the pressure at different points far from the initiation point. I suppose that is base on the distance, but is this distance in straight line or is the shorter distance following the workings ?

MArtin

thanks Martin

Thanks MArtin. I am doing that but somehow I believe that water should to be taken into account for the heat simulation. Does a fully flooded area impact the heat simulation?

Hi

How can I add on the same section a man door and equipment door?

Martin

Hi

How is the best way of adding flooded areas of the mine into VentSim?

1- Fully flooded areas

2- Not fully flooded areas

MArtin

ok, thanks Martin

OK, thanks Martin

Yeah, I need to update the version, but for now that will do.

Cheers

Martin

Thanks Martin

Hi

Is it possible  to get screenshots at set times from a simulation having ventsim minimized, for example when you are doing others things in the computer and the simulation is running in the background?

Regards

Martin

Hi

Could you explain the differences between running the simulation with and without the "Apply Diffusion" ticked, please?

Regards

Martin

Hi

Do you know where I can get more information about other combustion fuels properties?. My ventsim doesn't have hydraulic oil on the database.

Regards

Martin

Thanks Florian

I've done that but results are not what I was expecting that's why I was looking for a different way and though that I could simulate the explosion by injecting a big volume of gas in a very short space of time, but no luck.

Thanks

Martin

Happy New Year

I can't get this to work.  Do you have a more detailed step by step process?

See my setup in picture below. When I run the dynamic simulation nothing comes back, 0 pressure. Any idea why?

Martin

Hi

I am trying to simulate a fire outside the intake of a mine  (around 10m away).

Any suggestioins about best way to set it up?

Thanks

Martin
