    Thanks in advance for letting me know if Cantera can do this and if so how
    Bryan W. Weber
    @bryanwweber
    Hi @MarkusLohmayer Yes, you can do this, and yes you’ll need an input file
    Fortunately, one is already included with Cantera. This script should get you started:
    import cantera as ct
    gas = ct.Solution('air.cti')
    gas.TPX = 300, 101325, {'Ar': 1.0}
    If you have other questions, please feel free to post them on our Google Users’ Group: https://groups.google.com/forum/#!forum/cantera-users
    This channel is not monitored very closely, so you’ll get a faster response on the Google Group

    Hi, I have a veru basic install and usage question
    I have isntalled cantera using the launchpad ppa on 16.04 Ubuntu
    However I can't use cantera from python3 , due to this error undefined symbol: _Py_ZeroStruct, when importing
    I could only find these two threads, but I couldn't understand how to circumvent this problem without completely nuking my install or installing conda.

    It is going in python-2.7 directory
    /usr/local/lib/python2.7/dist-packages/cantera/, nothing is in python2.5/dist-packages

    @fedvasu Please post your question on the Google Group, this channel is not closely monitored and you’ll get a better/faster response from the Google Group

    @bryanwweber Would it make sense to remove Gitter from the Cantera docs? Or do you think this platform provides value? I've become skeptical of my old belief that Gitter would be nice to have in addition to the Google Group.
    Bryan W. Weber
    @bryanwweber
    I was thinking about that yesterday, @wandadars
    I think it makes sense to keep it around. The README is very clear that questions shouldn’t be posted here...

    Is there any tutorial on HCCI simulation with cantera for python ?

    Does anyone know how Cantera calculates "forward_rate_constants" I have only one reaction above
    and it seems Cantera returns the value, which is different from basic equation kf=AT^b*exp(-Ea/RT)
    image.png
    It returns
    gas1.forward_rate_constants
    Out[38]: array([2.78742811e-11])
    ArnoBetsy
    @ArnoBetsy
    which is different from k1 or k2 above

    @decaluwe
    @apoo7rv I am not aware of any that the project itself hosts.
    Steven C. DeCaluwe
    @decaluwe
    @ArnoBetsy FYI, this type of question is probably more appropriate for the user's group. Best I can tell, the k_fwd ought to be 8.5629e-10. But it would be easier to evaluate with the actual input file. If you do pots this on the user's group, please do not attach screenshots (they can't be searched or read by screen-readers for visually-impaired users), but either attach the files (preferred) or copy and paste your script. Thanks!
    ArnoBetsy
    @ArnoBetsy
    @decaluwe Thanks for your kind suggestion. I will use the user's group then.

    Any idea on implementing Jax (or autograd) with Cantera. Therefore, we can easily perform some sensitivity analysis, jacobian matrix evaluation.

    @rwest
    The best place to look (and then suggest) would probably be https://github.com/cantera/enhancements
    This, for example, looks like it’s a bit related, but taking a different approach: Cantera/enhancements#19

    @jiweiqi
    @rwest Thank you, Richard. The link is what I am looking for.

    @bryanwweber
    @SanchitUke We have several issues marked as good for new people on Cantera/cantera, Cantera/cantera-website, and Cantera/enhancements. Sometimes we use the tag help-wanted.

    Hello
    anyone has idea about dealing with "fmt missing" when using scons build command?
    @stalukdar751 Hi stalukdar, same here! Did you manage to solve it?

    @Serenade600
    anyone met the problem "unknown type name SUNDIALS_INDEX_TYPE"? seems like in subdials_config.h under cantera/ext/sundials, there is no definition about "SUNDIALS_INDEX_TYPE"
    Weiqi Ji
    @jiweiqi
    Hi, anyone has thought about build a Julia wrapper of Cantera using clang.jl? Something like Sundials.jl
