[piccinini]

Does any one know what could be causing this error?
I'm running reactingFoam solver.

Thanks.

Floating exception

hi

it is the problem of boundary conditions....

[hamburgFoam]

hey,

I was able to reproduce a similar error when I either set all the initial mass fractions to 0 or all the mass fractions were set to 0 at any boundary.
look at the Ydefault or other spezies files you set up.

Dear guys,

Do you know how I can download the tutorials of version 1.6 of OpenFOAM solvers e.g. reactingFoam? I mean, when you install OpenFOAM it automatically provides some tutorials for some solvers, but for some of the other solvers there's no tutorial, so I just wanna know how I can get to those ones specifically for version 1.6.

I look forward to hearing from you at your earliest convenient time.

Thanks,
Sina

Dear shajitah,

The reactingFoam solver is already inbuilt in the OpenFOAM 1.6 version.

Dear Naveen,

Thanks for your quick reply. I know the solver reactingFoam exists, but I'm looking for a tutorial which is directly corresponding to reactingFoam. I have found a reactingFoam tutorial for version 1.0 on internet, but it doesn't work on version 1.6. I'm roughly sure that there would be a tutorial for most of the solvers, but can't find anything for reactingFoam!

Regards,
Sina

Dear guys,
I have the same piccinini's problem.
I am using OpenFoam 1.7.1.
I have a simple methane-air non premixed combustor and used a one step mechanism for CH4 (as the counteFlowFflame2D tutorial using reactinFoam) and so I specified in my 0 directory CH4, O2, N2 and Ydefault.
In these files the mass fractions are not set all to 0.
Could you explain me what should be wrong?
I attached my 0 folder.

Regards,

Daniele

There is a tutorial for reactingFoam available on the wiki:
http://openfoamwiki.net/index.php/Tu..._firstTutorial

with a write up available at the following link:
http://www.tfd.chalmers.se/~hani/kur...actingFoam.pdf

The tutorial uses a single step reaction for heptane while the write-up uses a 2 step reaction mechanism for some fictitious species (they way it is done sheds light on how CHEMKIN works).

Greetings oll,
I am using OF-2.2 and tried to solve my case using reactingFoam solver with PasR model . i am getting the temperature profile almost as required but i am not getting the mass fraction of the products as desired . its coming almost double of what i required.

i checked my BC's many times and i don't think there is any mistake . i am attaching the files plz have a look and tell me then where i am doing wrong ??

Thanks in advance
