Hi in case file I have this a) Geometry and b) Domain :

[Rob]

If you want a point value use a point surface in Fluent. If you labelled the bus interior fluid region as being separate from the outside you can also create planes/iso-surfaces with the cell zone selected for a view that just considers the bus.

A plane surface of parcial results;


The iso-surface shows in contour does not shows higher values of fraction:

the point surface is not visible. I tried with CFD post but opening .dat result shows error "Unable to checkout license"

[Germanchoacr]

Thanks Rob for replying, if fora point value use a point surface I am going to get a puntual color for reading in the scale of color, not a exact number that is what I need.

I can now get license with CFD post but can not reach this calculation:
I reach until location that can not be changed neither the view 1:

[Rob]

In Fluent create a point. Then use the surface integrals to find the value at that point, vertex max is usually a good starting point. The second contour looks to not have the filled option ticked. You may also want to limit the range to local area (ie in the bus). Remember, the high NOx values will (hopefully) be outside, and a much lower concentration inside the passenger cabin.

The NO simulation finished with a little change, and without gas inside the bus, and with particulate matter 2.5 and CO yes other persons got the exhaust pollutant inside that, what could happened?

[Rob]

Looking at the plot, and assuming the bus is the bit with the "holes" in the surface I don't see why the NO concentration stays along the domain side. Are you sure it's correct as a NO concentration of 0.5 is likely going to be lethal! Change the scale to 0.0 to 0.1 and see how it looks.

Hello Germanchoacr how can I reach you? I have some questions regarding the simulation!

Hello, I'm given the following initial conditions inside car of volume 3.4 m^3:

I'm facing problems in  implementing  these conditions in fluent,??? any help will be appreciated!
