help with reactingFoam
Does any one know what could be causing this error?
I'm running reactingFoam solver. Thanks. Code:

reacting foam problem
hi
it is the problem of boundary conditions.... |
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. Ilja |
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. Regards Naveen |
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). |
mass fraction of products
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 :) Regards , Sonu |
