Hi,
In openFoam 1.4.1, if Ydefault has an initial value of zero the chemkinReader does not work. I get the following error by running dieselFoam on the aachenBomb without changing anything:
Case : aachenBomb
Nprocs : 1
Create time

Create mesh for time = 0

Floating point exception


However, if I initialize the Ydefault with a small number it works. I checked OpenFOAM 1.5, but there is not such a problem there. Is this a bug in 1.4.1 that has been fixed in 1.5 version?
Cheers,
