Hello, I am a beginner trying to figure out the temperature limitations on Canteras chemical equilibrium calculations. From what I understand Cantera uses the...
Tomas, Cantera can use whatever thermo data you provide in the input file. All you need to do is provide high-temperature thermo data in order to carry out...
The temperatures at which failure occur are not necessarily below the polynomial fit ranges; in that case, I understand that there may be problems. I am using...
Hello. I am using Cantera 1.5.5 with Python 2.4 on a Win XP computer, but I have not used Cantera much. I tried to create a Reservoir "res = Reservoir(gas)"...
OK. I figured it out. Apparently, I should have "from Cantera.Reactor import *" before I use any reactors, reservoirs, etc. Well, you learn something new...
Well, just when I was getting productive, I ran into a problem with Cantera/Python. I had Cantera working on this XP workstation, but I was trying to install...
Mark, I suspect the problem is that the Cantera Python extension module was built to link to one version of the Python DLL, and can't be used with a different...
Dave, Thanks for your assistance. When I run the .pyw in IDLE there is no error given. Likewise, if I cut and paste the whole command in a DOS window, it...
Hello, I need to build a large network of reactors but I am concerned about the CPU time it takes to run a simple reactor network Cantera file. When my ...
Gerard, The CPU time is nonlinear in problem size since the governing equations for all reactors in a network are integrated together using an implicit ...
If I solve the equilibrium problem using a speficied temperature, I am able to solve it easily for the entire range of enthalpies that I wish to cover. ...
One option is to write an outer loop that iterates on T until the desired H is attained. A Newton-like algorithm would probably converge very quickly. With...
Arief, All you need to do is replace h2o2.ct by an input file that has thermo data for N2. One simple way is to import the data and reactions from ... ...
Hi, I'm trying to install Cantera on my Linux machine and when I run the configure script, I get the following messages: checking for Fortran 77 libraries......
Dear Dave, Following your advice, a .xml file was produced containing the information below (demarcated by ****.xml file****, *****end.xml file*****). My...
Arief, ... In the file I sent you, I prefaced the species entry with "gri30: ", and also the reactions entry. This means that Cantera will look for these...
Many thanks Dave. It works now. Further question: Some of the reactions in the kinetic scheme are tagged with [options = 'duplicate']. These reactions appear...
A duplicate reaction means that the reactant and product stoichiometric coefficients are the same (or differ by a constant factor) for the two reactions....
But why do people add the same reaction twice to the scheme? When the chemical equations are viewed upon as a system of algebraic equations, the repeated...
In some cases, the same reactants may react through 2 different pathways. Suppose for example that 2 diatomics react very differently if they collide...
Dear Dave, Suppose that I have a laminar flame solution at a particular combination of (p,T,phi,Y1..Yn). How can I use this solution at an initial guess to...
Arief If you have a existing flame object ("flame") that you have just completed a solution you can change the boundary conditions (T,Y) through the ...

Which version of Visual Studio.Net is needed to compile cantera? Our systems administration gave me Visual Studio.Net 2002 Professional. Arief...
I've noticed that a surface site density can be specified in the cti file for an interface. Does anyone know of a method accessible to the 'interface' class...
