Dear Prof. Goodwin as Martin said, it would be great if a Cantera workshop would be held in Europe, especially in conjunction with the Combustion Symposium. I...
Hello: I am having trouble getting the ck2cti utility to work. I seem to be running into two problems. 1) When I run with all three input files, the program...
Hi, I ran into this problem a few months back..I believe its a software problem..the latest version of cantera / python does convert the files when the...
Hi, The previous versions of Cantera did seem to give troubles converting mechanisms when all three files (including transport mechanism) were included..but...
Hi all, I was trying to use Graphviz to get path diagrams for my mechanism..Since my mechanism is huge, the diagram is unreadable..I was reading up on the .dot...
Does anybody know how to change MATLAB demo catcomb.m so that it works? I built a mechanism that uses reactions from ptcombust.cti and gri30.cti. I have the...
I have put the current version of the ck2cti.exe program for Windows on the User's Group site under "Files". If you are working on a Windows PC and have...
I'm not sure if this is the problem, but try setting USE_SUNDIALS to 'n' in 'configure' and then re-run 'configure'. This should be the default, but in the...
... I tried it but didn't work. I manage to compile the same sources on another machine (gcc version 3.2.1 20030202 (Red Hat Linux 8.0 3.2.1-7) on 32bit Intel)...
I think some work needs to be done to port Cantera to 64 bit machines. Type "doublereal" is defined in config.h, and can be mapped in principle to "double" or...
I am new to Cantera and I have couple questions. I am trying to model catalytic combustion of methanol+hydrogen mixture as a nonisothermal tubular reactor with...
Hi People, I converted the lnll kinetic mechanisms to cantera (Ethanol_mech, for example) without troubles as shown in the attached log file. But I have...
From Python, try to import the problem mechanism: from Cantera import * g = importPhase('Ethanol_mech.cti') It may fail, but the error message will likely be...
Unfortunately, I do not have access to Mac or Linux platforms but I found out that if I run catcomb in Python it works. Lucy ... ptcombust.cti and ... demo in...
David, I'd be excited to have it in Germany. I'd even be willing to do a presentation on the work that I've been doing using Cantera. I would also love to...
Dear Cantera users, I have been attempting to utilize the Konnov mechanism for the simulation of stagnation point flames. So far, I have been unsuccessful at...

Jeff, Would you be able to post the flame operating conditions and/or the driver routine (python or matlab) which is stalling at 20 to 30 grid points to the...

Dear Cantera users, is ck2cti able to read global reactions in chemkin files? For example, if I give a reaction like this one: CH4 + 2 O2 => CO2 + 2 H2O 8.3e5...
Max - You need forward slashes in your chemkin file: FORD /CH4 1.8/ Also, be sure you have a recent version of Cantera, since support for "FORD" was only added...
Dear Prof. Goodwin, I found in 'gaskinetics.cpp' that reverse rates are only computed when doIrreversible=true. Shouldn't it depend on the reaction-flag, e.g. ...
Ulf, Actually, it does precisely what you say it should do. The array "m_rkcn" holds the reciprocal of the equilibrium constant for the reversible reactions,...
Dave, but when I look at "m_rkcn" in getRevRateConstants() it holds the reaction-difference of chemical potential (delta_r_g). While equilibrium constant is...
Hello, I am trying to run a NPFLAME1 - A nonpremixed counterflow flame model in Python at higher pressures than 1 atm. In this model I got a problem to set the...
Dear Dave and Group, I'm trying to use the "size" attribute of a species to specify the number of sites that a surface-bound species occupies (n_k in eqn. 3.4 ...
