Hello,

has anybody tried linking Cantera 1.8b to OpenFOAM 1.6?

Hello,

no up to now the library is only available for 1.5.x. An update is planned.

Regards, Markus.

Default Piloted flame case - question

Hello Michele:

In an earlier post you mentioned (Oct 2009) that you had successfully run a piloted flame test case with the steady solver; is this something you could share?

I am trying to implement something similar, and while the reactingFoam solver works, the transient approach is very computationally inefficient. I was able to run the test case with alternateSteadyReactingFoam, and I am struggling to make a CH4 flame case work.

Thanks so much!

Kind Regards,
-aat

Default error running alternateSteadyReactingFoam on ubuntu

Hi,

I am using cantera1.8 and sundials2.3.0 as described on the wiki page with OpenFOAM-1.5-dev on Ubuntu operating system.

I had problems in getting CanteraThermosChemistry compiled with an error that cantera/kernel/CVodesIntegrator.h not found. I checked the cantera installation and found that there was no file under ..../installCantera/include/cantera/kernel/CVodesIntegrator.h. I could find a different file CVodeInt.h under the same path and therefore changed the filename from CVodesIntegrator.h to CVodeInt.h in the following files.

canteraChemistryModel.C
canteraLocalTimeChemistryModel.C

This allowed me to compile the canteraThrmosChemistry and other solvers. But, when I try to run the example by typing alternateSteadyReactingFoam or alternateReactingFoam, I get the following error.

alternateSteadyReactingFoam: symbol lookup error: ....../libcanteraThermosChemistry.so: undefined symbol: N_VNew

I couldn't file any variable named N_VNew. Am I missing something while compiling or do I need to make any additional changes to the canteraThermosChemistry source files.

Any advice is greatly appreciated.

thanks for your time,
Bhadraiah.

Hello,

it seems like there is a problem with the Sundials installation. Check if Cantera uses Sundials correctly by running the demos (e.g Cantera python demos).

Hi Markus,

Many thanks for your inputs. It indeed seems to be an issue with sundials. I did check the demos under Cantera previously and they ran fine. So I was not sure what the issue was. Meanwhile I found your other post at the following URL as well.

http://www.cfd-online.com/Forums/ope...de-solver.html

Based on the posts in that article, I started from scratch and compiled sundials with --enable-shared option (the wiki only said CFLAGS=-fPIC). I was able to go through the rest of the installation as per wiki without any issues. The alternateSteadyReactingFoam and alternateReactingFoam now run fine without any issues.

Thanks again for your inputs.

regards,
Bhadraiah.

So there are 2 parts:
1.) alternateChemistryModel A Library that allows the inclusion of alternate chemistry engines in solvers (allowing still to use OF chemistryModel)
2.) canteraThermosChemistry A Library that makes it possible to use Cantera in OpenFOAM

The libraries can be used by the solvers alternateSteadyReactingFoam and alternateReactingFoam. There are also examples included.

We had some issues to get Cantera running properly. I used the 1.7-CVS version. If you encounter problems with the standard version we can put a tarball of a running Cantera version onto the SVN, too. But Cantera 2.0 was announced and so we try to avoid unnecessary work

The main reasons for using Cantera are:
-easy access to thermochemical data and functions
-cantera has an excellent lexer for Chemkin-input
-you can use all transport data (viscosity, diffsion, heat transfer) from transport data which is often available with reaction mechanisms (e.g GRI-3.0)
-ideal reactor networks can be constructed and solved efficiently and stable with the CVODE stiff ODE solver package

I hope that helps and you find the tools valuable.

Regards, Markus.

Hi Marcus,

is there a way to use alternateReactingFoam with Openfoam-1.6 yet?

I have tried to make it run, but compiling alternateChemistryModels i found that he wants some file only present in the openfoam-1.5. .

So I linked it in the options-file but then another error message comes up, with which i can't deal

Or is it invain to try anyways since cantera.1.8 still wont work with OF-1.6 ??


have a nice weekend!

Hello,

no Problem with Cantera-1.8 but some classes changed in OF-1.6 and it is not straight-forward to do the upgrade. As soon as I find some time I will continue the work.

Regards, Markus.

Hello Markus,

thank you for your great work. I tried to install cantera as you showed in your tutorial, but I could not run the cases. Seems to be a conversion problem. Could you give me a hint?

Hi,

I would like to add one additional equation in Cantera.
Is that possible to add one more additional equation in One D simulations In Cantera?

Hello All,
While running the transient case that came with AlternateChemistry, I received a warning that reads the following:

--> FOAM Warning:
From function canteraChemistryModel:: calcDQ(volScalarField &dQ)
in file canteraChemistryModel.C at line 321
Calculation of dQ is not yet verified

Is this warning expected? Could someone please explain what it means and what are the potential implications?

Thanks,
Sunny

This is hardcoded in that method. It means that the method is not fully validated and you should not believe the numbers in the field dQ.

The cause is that it was coded by the programmers (us) there. Because we never verified whether the results of THAT method are correct (because we didn't use these results). If it bothers you comment it out. If you need the results verify it.

Actually I get also this one:

--> FOAM Warning :

should I be worried?

I'm pretty new in CFD so I ask sorry if maybe I do trivial questions.

Currently I'm doing a case with a premixed flame and I use alternateReactingFoam . It works, but I have some doubts:

-In the file Gri30.cti there a function called "transport" and I can chose to leave it empty, set it "Mix" or "Multi"... but it looks like give the same results even if i set it differently. what does it do?

- my case is laminar so I switch turbulence off but I can't really understand how I should set the transport proprieties (mu lambda etc) in the RASProperties file or how OF calculates them.

Thank you very much!!!

1) There are different models to obtain the mixture-averaged transport properties implemented in CANTERA. For more information have a look at the Cantera documentation/ source code. I can recommend this document

http://sourceforge.net/projects/cant...s.pdf/download

For further questions regarding CANTERA please refer to proper forum

http://groups.google.com/group/cantera-users

Furthermore I suggest you to check out the demos and tutorials provided with CANTERA.


2) If you use the alternateChemistry-library in "CANTERA-mode" (i.e. chemistryEngine canteraChemistryModel) the chemistry, thermodynamical, and transport data is taken from the cti-file. If you use the alternateChemistry-library in OpenFOAM-mode (i.e. chemistryEngine chemistryModelProxy) all the data is obtained as usually done in OpenFOAM.

Regards, Markus.

Hi, again me...

I'm trying to make cantera work whith openfoam on a 64bit, 40 processors server that runs on RHEL5.3.

So far sundials2.4 and cantera look like they work ( i don t have any problems with the testProblems in cantera).

I followed your web guide to instill the libraries,when i wmake alternateChemistryModels I don t have any problems but when I wmake canteraThermosChemistry I get this error:

/share/cantera-1.8/include/cantera/IdealGasMix.h: In copy constructor ‘Cantera_CXX::IdealGasMix::IdealGasMix(const Cantera_CXX::IdealGasMix&)’:
/share/cantera-1.8/include/cantera/IdealGasMix.h:40: warning: base class ‘class Cantera::IdealGasPhase’ should be explicitly initialized in the copy constructor
/share/cantera-1.8/include/cantera/IdealGasMix.h:40: warning: base class ‘class Cantera::GasKinetics’ should be explicitly initialized in the copy constructor
/usr/bin/ld: cannot find -llapack

make: *** [/home/sahm/OpenFOAM/sahm-1.5/lib/linux64GccDPOpt/libcanteraThermosChemistry.so] Error 1
[sahm@cmtl canteraThermosChemistry]$

actually the llapack lib is in /usr/lib64, i tryed to change the path in canteraThermosChemisty/Make/options like below:

LIB_LIBS := $(LIB_LIBS)/../lib64 \
-llapack -lblas \

but I still get some errors.

actualy I don t have a clear idea what above options file does.

Do you have some tips?

thank you very much

Hi everybody,

In order to call the "speciesData" I use these lines in reactingFoam.

reactingMixture& multiMix = (reactingMixture&) thermo->composition();
PtrList<reactingMixture::reactionThermo> speciesData = multiMix.speciesData();

but I have some troubles to do the same with alternateReactingFoam / cantera solver.
Does somebody know how I can access to the "speciesData()" using alternateReactingFoam?

Thank you!!
