chemkin
Hi all
I`m aware that chemical kinetics isn`t strictly a subdomain of CFD, but since quite a few subscribers of this site deal with combustion, I figured that I might as well air a problem I encountered when using Chemkin. Here goes. When using a certain reaction mechanism in the PSR (perfectly stirred reactor) program, I get the following error message: "Different # of species in cklink and data file." Perusal of the psr.out file reveals the last line (before the program crashes) to be "The balance matrix has 5 rows and 4 columns." The odd thing is that the Premix and Senkin programs function correctly when the same reaction mechansim is utilised. If anybody can shed any light on this problem, I`d be really glad to hear from them. Thanks in advance, richard |
Re: chemkin
Just thought I`d mention that this problem does not exist with other reaction mechanisms.

Re: chemkin
Check everything carefully.

Just for future details if anyone searches this, like I have. I know it's an old topic.
For me, it fixed itself when I added a "prod" line in. Or maybe two extra prod lines. Example, add say, prod Ar (argon) in there. Play around with different number of lines of prod, reac. |
The fortran source need to have a same number of defined elements with the number of used elements in the reaction mechanism.
The message shows that you should modify the number of elemets in Chem.DAT file. |
