I'm not sure. It's not my fiel

I'm not sure. It's not my field. But you could give a look to the papers on dispersion in the environment where flacs calculations are presented.
They validated their models on large scale data and...

Hello, dispersion models toge

Hello,
dispersion models together with k-eps turbulence models are commonly used to predict the diffusion of pollutants in limited portions of athmosphere like a part of a city where an accident...

OK. But hook() just adds an element at a time to the ptrList.

What I'd like to do is to let the user set the number of species, their name and then insert the diffusivities.
The speciesTable...

Sorry. It's a typo again.
The actual code is:

List<dimensionedscalar> Dl
(
speciesProperties.lookup("Dl")
); //This is line 58 in createFields.H

but the error is the same.

Thank you Niklas. Defining

Thank you Niklas.

Defining a speciesTable, I can store the names of the species (I don't actually need this, but it makes the solver more user-friendly and the results easier to be read) and use...

Hello, I'm trying to add mult

Hello,
I'm trying to add multiple species to the solver but I have some doubt on the usage of the ptrList.

I defined a ptrList of volScalarField and I called it Y. How can I set the MUST_READ...

Yes it would be very useful to

Yes it would be very useful to see the code and to put it on the wiki.

For initialization, there is an example of patching utility in the manual, where the dam break is presented.

I plan to...

Sure David.

I didn't implement the wind profile. However there are two threads on inlet profiles here:

Thank you Niklas. The assum

Thank you Niklas.

The assumption of using only the turbulent diffusion is OK in my case in an open environment, where the wind plays the biggest role. I don't think so in a closed one.

Thank you for your answer. My

Thank you for your answer.
My problem is not with the transport equation, but with the managment of a mixture of more than two components.

If I'm not wrong, I found something similar to what i...

Hello,
I would like to model the dispersion of pollutants (non-reacting) in the environment (air).

The air flow is described as a turbulent ideal gas. Species transport is described with the...
