    Thank you @bryanwweber, before I start I have a doubt, I go through GSOC19 ideas list. I found that most of the ideas are also a part GSOC 18 ideas list. Are the GSOC19 ideas list updated?

    Thank you :)

    After activating the environment you can execute
    conda install notebook
    in the same environment and then run jupyter notebook, then it should work

    Hello, I am Rounak Agarwal, a third year CSE undergraduate at IIIT Jabalpur, India. I am looking to contribute to Cantera under NumFOCUS as part of GSoC'19. I went through the ideas listed at https://github.com/Cantera/cantera/wiki/GSoC-2019-Ideas
    I am interested in the ideas Improve Jupyter notebook integration.
    I am familiar with Git and Github having contributed to Open Source projects before. You can read more about my previous Open Source contributions here: https://medium.com/@agarwalrounak
    I also have a lot of experience with Python as most of the projects I have worked on involved Python. For example https://github.com/agarwalrounak/Codigo_Maestro and many more on my Github profile: https://github.com/agarwalrounak
    I would like to know how I can move ahead with the ideas so that I can prepare a proposal.

    Hello, I want to know if modules associated with ions, such as 'ion_free_flame', are available in cantera installed through conda. I cannot find it in the example folders of my computer. Thanks

    Hi everyone! Hope you are doing great! This is just a reminder that the student application period for GSoC has begun. The final deadline to submit students applications, to be done strictly via the official GSoC platform, is April 9th 18:00 UTC.

    Hello everyone, I have written a proposal to work on revamping Mixmaster for GSoC. Kindly review it and suggest any changes. Proposal Link: https://docs.google.com/document/d/1KJ4_QIYXdXOn6D1Qg6DUjuatbyJYgqFi1_V74M_DsYA/edit?usp=sharing

    @bryanwweber
    @tangy11 Yes, all of the Python modules are available from the conda package. The examples folder can be found by following the instructions here: https://cantera.org/examples/python/index.html

    I am getting error trying to compile cantera
    (Win 7 64-bit, Anaconda, python 3.6.6)
    WARNING: Not building the full Python 2 package because the Python 2 
    interpreter 'python2' could not be found or a required dependency 
    (e.g. numpy) was not found.
    ERROR: Could not execute the Python 3 interpreter 'python3' or a 
    required dependency (e.g. numpy) could not be found.
    I don't know when it is trying to use Python 2

    @refactormyself
    In case any newbie like me is facing error relating to python3 command when you follow the build instruction and your build env setup. The default command for python 3 is python3. Use python3_cmd = 'python' to change it. See here

    Hello everyone! I am Thanasis Mattas, senior student at the Physics department of Aristotle University of Thessaloniki in Greece and I am strongy interested in Cantera and GSoC-2019. I have already introduced myself at the mailing list, so I keep this one breef!
    I have built cantera on my system (ubuntu 18.10), but an error occured while trying to compile, for example while, the simple C++ programm at the cantera.org: https://cantera.org/tutorials/cxx-guide/simple-example.html#sec-cxx-simple-example
    the command I run:
    g++ -o combustor -pthread -O3 -std=c++0x -I/usr/local/include -L/usr/local/lib -lcantera -lsundials_cvodes -lsundials_ida -lsundials_nvecserial combustor.cpp
    Thanasis Mattas
    @ThanasisMattas
    And the error:
    /usr/bin/ld: /tmp/cc25A0LA.o: in function simple_demo()': combustor.cpp:(.text+0x7a): undefined reference toCantera::newPhase(std::cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >)'

    collect2: error: ld returned 1 exit status
    I followed tha manual build-from-source with scons and the conda build in a differend env, and the same error occured while runnig the command activating both envs. (Default -> pyhton3.7.3)

    @ThanasisMattas
    Can anyone please help! Thank you!
    Bryan W. Weber
    @bryanwweber
    @ThanasisMattas Where did you install Cantera? If you didn’t install Cantera, then you’ll have to include the build directory into your include and library search paths
    Thanasis Mattas
    @ThanasisMattas
    If it is ok, I will transfer the issue properly at Cantera Users' Group
    Bryan W. Weber
    @bryanwweber
    @ThanasisMattas that would be preferred :-)

    There are a few hours left before the deadline (April 9 18:00 UTC). Please make sure you submit your final proposal (not draft) as well as a proof of enrollment in an eligible university program by the deadline. Google is very strict about deadlines.

    I am a newcomer,and may i ask. If I use the .cti file, either gri30.cti or air.cti can't run,they will return CanteraError. But it works with gri30.xml. Do i need additional files to use .cti files?
    Thank you very much for any help.
    Thanasis Mattas
    @ThanasisMattas
    @QBPA Hello! I had the same problem. Have you installed all the dependencies? You need numpy for ct2ctml (witch makes the conversion) to work. If you use anaconda: conda install numpy (check version first - for python2 or 3). If you dont: 1. sudo apt-get install python-pip
    1. sudo pip install numpy (again, check the version first). If that is not the case, provide more info, like your system and your installation method.
    QBPA
    @QBPA
    @ThanasisMattas Thank you for you help. But i have install numpy with conda, and successful execution of ck2cti. and i tried to update the numpy and another error has caused.
    Thanasis Mattas
    @ThanasisMattas
    @QBPA You can downgrade I think. Ok. Maybe someone else can help you. In my case, though, I actually did install numpy with conda but the python interpreter wasn't set to the conda env directory. I think that was the cause of the error. After installing numpy with apt-get, I could then use .cti files.
    QBPA
    @QBPA
    @ThanasisMattas OK,i will try to repeat the reinstallment. Thak you for you help.

    I have reinstalled conda several times, and I still have the above problem. I use win7 with conda. and can see cantera 2.4.0 and numpy 1.16.3 after using the pip list command.

    @bryanwweber @decaluwe @speth can i get some insight about why my GSoC proposal didnt got selected for this summer?
    Bryan W. Weber
    @bryanwweber
    Hi @CyberDrudge Unfortunately, we were only assigned one slot from Google this year, and we were very limited with our mentoring capacity. It was a tough decision with a lot of good applications. Thank you for your effort on all the pull requests you’ve made! We hope that you will continue to contribute to Cantera in the future.

    @ThanasisMattas Hello,I am a newcomer, and I had a problem. I can use lots of function except the function of AxisymmetricFlow, and the error: Undefined function or variable 'AxisymmetricFlow'. I can not even run the examples which include the function of AxisymmetricFlow, but can run others. Thank you very much for any help.
    Can anyone please help! Thank you!
