Hi Michael, You can either modify the preconfig file with user configuration options such as USE_NUMERIC, or you can create a preprocessor that defines...
Hi Alejandro, I think Cantera or the python interpreter of cti files may read/write files to a windows system directory. This causes problems when the user ...
Hi Dan, I have fixed one aspect of this problem within the CVS code. Previously, after initialization, if the mole or mass fractions were not set in the CTI or...
Hi Harry and Dan, I checked out and built Cantera from CVS today, but am still getting very strange results from a simple Fortran example problem: PROGRAM...
Hi Mike, When I ran your program, adding the line double precision meanMolarMass, intEnergy_mass I obtained: 28.8507043 -84549.2746 That must mean there is an...
I have been trying to simulate a piston using cantera in C++. I have succeeded in creating walls etc.. I am however stuck when it comes to using the Fourier...
Hi users, I would like to perform several calculations with free_h2_air.py and extract laminar flame velocities at different phis and temperatures. The code...
I've noticed some differences between the behavior of Cantera simulations generated from the GRI reaction mechanism with those from the H2O2 subset that's in...
Hi, I'm trying to get information on how to use the "solve" function that can be used to solve a steady-state problem by combined damped Newton iteration and...
When we added the line below: double precision meanMolarMass, intEnergy_mass to our code, things worked fine for every call. Was unaware that subroutines...
The reason you need to declare it as double precision is that it begins with "m" (or "i"), so Fortran implicitly assumes it is an integer function. The best...
The problem seems to be that you are calling setSpeciesFluxes with zeros for the array sizes. The third parameter should be the length of the grad_X array, and...
Dera friends I am a new user of Cantera and I would like to ask you how to calculate heat of combustion and heat of reaction of H2-air mixture I look forward...
Hi, I am new to cantera and although i went through the steps of installation properly, i am still unsure if i have completely installed cantera. I installed...
Hello, running the flame1.py burner stabilized flame simulation I recognized that the concentration of H2O (water) is at z=0 about a third of the final...
The initial mass fraction of the species at z = 0, will in general not be the same as the specified mass fraction for the flame models because the boundary ...

The non-zero product concentrations at the inlet are real, and are due to upstream diffusion of the products. This effect will be more pronounced at low...
Mea culpa! It is no bug, but a very nice piece of software! I recognized the underestimated effect of back-diffusion in the calculations playing a little bit...
Guillaume, Have you tried changing the loglevel in the equilibrate command? If loglevel is > 0, an html file will be written with debug information. If...
Jonathan - I'm getting a similar issue with the Mixture class on a Mac (OS X 10.4.8, Matlab 2006b, Cantera from CVS): The errors are (among other things)... ...
I have found the error. In the final state, the smoke's temperature is about 850K, and the thermo properties of condensed-phase speciesH2O(L) are defined...
Hi Ashish I'm struggling with the same Problem as you did! When I install the progs. in the same order as you did and I get this Error Message. If you have...
