Trying to use Cantera on windows 7 Professional 64bit using Matlab R2010b. Matlab crashes as soon as function: advance(reactor, t) is getting executed. I have installed Cantera 1.88 and Python 2.6 (both for 64 bit windows). The same code works perfectly fine on a 32bit machine where i have Cantera 1.7 and Python 2.5. I'm using the correct executable(ctmethods.mexw64) file for 64bit machine. Any help will be appreciated. about cantera HOT 12 CLOSED

Please provide an example mechanism and script which produce the error.

[deleted comment]

I run in to a similar issue. I receive it after running the 'air' command. For 
the installation, I followed the instructions in the link, 
http://www.me.berkeley.edu/ME256/InstallingCantera160r1.ppt. I'm using Windows 
Vista, Python 2.6, and Matlab R2010a. Some instructions have mentioned 
installing Numpy or Sundials, which I have not done. Is this required? Running 
any of the tutorials or commands produces a segmentation fault. A copy of the 
error is printed below. Running the command a second time produces the stack 
trace also posted below. Any help on this would be awesome. 

Thanks. 
Sunny

I noticed that you are running cantera on a Mac.  Could you please help me 
through the install process.

[email protected]

I have a similar problem. I compiled and installed Cantera on a 64-bit Windows 
(Vista) box with Python 2.7. When I invoke the "advance" command (on a 
ReactorNet object), the python program crashes (I do not get any tracebacks). 
Strangely, this does not happen in all cases. For example, if run the GRI30 cti 
file, it advances fine. But if I create a test case containing a single 
reaction (say, 2H2+O2 = 2H2O), the python shell crashes. The same test case 
runs fine with the 32-bit Cantera executable for Python 2.6. I am trying to 
debug the C++ code now to get more information that can be added to this bug 
report.

I'm also have a similar problem with all the Cantera functions where the 
Arrhenius equation has to be evaluated ("ydot" command for example). I have 
installed the proper version of Cantera for Windows 7 64-bit (at least 
according to what is claimed in  
http://stuff.mit.edu/afs/athena/course/2/2.62/www/cantera/install.html). 
Instead of Python I'm using Matlab 2007b. I have no problem as far as I run 
GRI30.cti file. When I try to run mine (2H2+O2 = 2H2O) Matlab crashes without 
any feedbacks. I've also tried to modify the GRI30.cti file in order to have it 
matching the mechanism I'd like to run, but no luck so far.
I didn't have this problem using Cantera still for Matlab2007b but on Windows 
XP 32-bit machine.

Any hints about that? 

Actually, I debugged this a bit, and found that the 64-bit windows program 
crashes when we run a reaction set that *does not* contain any fall-off and/or 
three-body reactions. If I comment out lines pertaining to 3-body and fall-off 
reactions in the code and then build Cantera, the simplified reaction set runs 
fine. So it seems like there is some problem handling a "NULL" array for the 
three-body and fall-off reactions. I'll post the lines that I had to comment 
out and maybe the dev group can help with this.

I tried as you suggested, but I still have the same problem. Moreover, it also 
appears if 32-bit version is used. Can you please attach me an example of what 
you did so to reproduce it?

What steps will reproduce the problem?
1 Any call within MATLAB to an 'rop*' or 'Rates of Progress' function using the 
default phase of the air.cti file or the attached air-highT.cti file. Note that 
the default phases of gri30.cti and h2o2.cti do function properly, and that all 
4 files function properly when run with Python 2.6.6

2. The test programs, which are modification of the demo files provided by 
Cantera, are attached:
'tut4_mod.m', 'tut5_mod.m', 'tut4_mod.py'


What is the expected output? What do you see instead?
MATLAB crashes with no ouput


What version of the product are you using? On what operating system?
Windows 7 SP1 Home Premium 
Cantera: Installed from cantera-1.8r444-amd64
Matlab: R2010a 7.10.0.499
Python: 2.6.6 64 bit using Numpy 1.6.1 64 bit


Please provide any additional information below.
Comment 7 from "[email protected]" suggests that the crashes are tied 
to a lack of fallof or 3 body reactions, however, all four files that I have 
tried had both three-body and falloff reactions regardless of whether they ran 
successfully or failed.

I fixed the problems with 3rd body and falloff reactions in r957. Both the 
Matlab and Python examples given by vaughantel1 work for me, so I think this 
will be resolved when the SCons branch is merged into trunk.

Having the same problems when implementing my own mechanism.

yarmond, how do i implement r947, I cant find GasKinetics.cpp in my 
directories.  Would I just save it in the private folder with the other cpp 
files.  I can find GasKinetics.h, but not .cpp.

Thanks!,
Ben

Ben: you would need to check out the source code from subversion (svn checkout 
http://cantera.googlecode.com/svn/cantera/trunk/ cantera) and compile Cantera 
yourself, or wait for an updated installer to be released in the near future.
