2. use the Flamelet-Model 2.1.x on my git repository. Its newer and some user-unfriendly setups are made there.

3. if you have the possibility use OpenFOAM 2.2.x couse I made a few output changes in the Flamelet-Model 2.2.x

Hi Tobi,

Thanks for the update i have started using Flamelet-Model 2.1.x but i i am not able to create PDF library with bigger chemical kinetics file.if the number of species/reactions are more it is giving an error like

I dont know whats happening while calculating the look up table. i was using a bigger chemical kinetics file for DME. It is working well with small CRECK kinetics and GRI Mech.

please help
Thank you
Hari

What is the maximum number of species that can be handled by OpenSMOKE_CHEMKINInterpreter.sh

when i run this, i am getting an error

terminate called after throwing an instance of 'std:ut_of_range'
what(): basic_string::substr
./Run.sh: line 1: 64711 Aborted


Please help

Thank you
Hari

Hi hayhari
I experienced the same problem, when I tried to use C1C16 polimi mechanism, Unfortunately I couldn't fix it.I think that due to lack of access to flamelet generation code
there might not be a clear answer for this problem.

Normally everything should work:

1. all species must be avaiable in the three folders / files

-> kinetics
-> thermodynamics
-> transportproperties

2. As bobi told you, there is not a clear answer for you due to the binaries.

Sorry

But if there are some users that want to programm with c++ the flamelet generation new I promise that I will work with you!

There are some nice c++ libraries for beta-pdf- calculations and so on!

Greetings to all!

Just passing by to give some news... looks like the CRECK Modeling team has gone pro! Check it out:

• http://www.opensmoke.polimi.it/
• http://www.catalyticfoam.polimi.it/

I found out from their main website: http://creckmodeling.chem.polimi.it/

Best regards,
Bruno

while excecuting OpenSMOKE_LookUpTable.sh.... what is the possible fix for this error..?



Thanks
Hari

[Tobi]

Hi Hari,

do you use the flamlet model from my github?
If yes I can not give you a solution for that. The problem (i mentioned many posts befor) is the binarys for the falmetlet generation.

Its not possible to have a look into that !!!
Therefor you are not able to resolve that problem!

But maybe there is a othre tool in the laminar tool?!

[Tobi]

Well the laminarSmoke uses a binary execution file too

[lcy]

thank you. the question is solved. I update the linux, and try again. Then it succeeds.

Hi Tobi,

I've posted here some questions about the flamelet libraries one and half month ago. And during that time, I was working on another model first and then on CANTERA to build my own flamelet librairies. Now, I've got the libraries and my next step is to be able to create an interface between the CFD solver and the libraries. I've one and half month to have interesting results... Is it possible?

Thanks

Yes the implementation of your Flamelets into the OF Solver is very easy. Is your code free ?

I am interested in that stuff.

[danz]

Hi Tobi,

Unfortunately, my cfd code is not free...
Now, I'm trying to create a module to read my library

Hi,

I have made a a complex geometry in fluent and exported to OpenFoam using Fluent3dToFoam.it is having 20 patches. Then i tried to do the simulation using Flamelet model then i got the following error..

I am relatively new to openFoam and not able to identify the reason for this error.

Also H in 0 directory is which enthalpy? enthalpy of formation??

Please help.
