Hi there,

I am very new to OpenFOAM and have been using it as part of my undergraduate thesis. I have been using the aachenBomb tutorial (under the sprayFoam solver) as a basis for my project, which is simulating the injection and combustion of n-dodecane.

I have created and successfully run the wedge mesh to convert it to 2D.

However, I am in the process now of converting the fuel n-heptane to n-dodecane to suit my case. I have been given two files to replace the chem.imp and therm.dat files in the aachenBomb case, that have been used successfully in openFoam4 for n-dodecane.

However, I am getting the following error message. I have not modified the files at all, and in their current form they work in openFOAM4.

nProcs : 1
sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).
fileModificationChecking : Monitoring run-time modified files using timeStampMaster (fileModificationSkew 10)
allowSystemOperations : Allowing user-supplied system call operations

FOAM exiting

Is this simply a formatting error being picked up by openFOAM? or something different between the chemkin readers of openfoam4 and openfoam5.
