Dear all,
I have an urgent problem and I hope someone can help I'm trying to simulate the reactingFoam-tutorial from OpenWiki, but I get the following error message running reactingFoam (blockMesh is okay). I use exactly the files uploaded, and I also tried my own case, but I always get the same error message. I would appreciate any suggestions...

Oh, I just forgot to tell you: I use Ubuntu Linux 9.10, OpenFOAM 1.6, Qt 4.5.2. And I really use the exact files without any changes given in the OpenWiki tutorial for reactingFoam. Has anyone else perhaps tried out this tutorial and found out, why this error is appearing?
When I use unset FOAM_SIGFPE, the simulation is running, but there's only mixing and the reaction doesn't take place... |

Hi,
First, the reactingFoam tutorial is a bit of a strange set up. It tries to simulate heptane burning with pure oxygen. Preferrably, the setting for the oxidizer inlet should be 0.23 O2 and 0.77 N2. I recall people having trouble with this before. Now, this error is maybe not related to that. Didn't you make any changes to the tutorial? When I try it on my OF1.5 I need to change a header of a file (well, not that important), add 'RASproperties', and fix the link to the chemkin-files. Regards, Kalle |
