I tried to run the tutorial aachen bomb with 1.6-ext but it crashes after a while with the error janaf out of temperature range. The same tutorial runs with out any problems in all other openfoam versions.

Go to line 289 in /src/lagrangian/dieselSpray/parcel/parcel.C
Replace it by scalar nKE = 0;
Apparently there is a problem with the turbulen kinetic energy.
Recompile the dieselSpray class with wmake -libso and than run the tutorial aachenbomb.
let me know if it worked out for you!
cheers peter

Hello all,

I am running dieselEngineFoam with spray. I am getting following error some time after spray injection. I checked the chemistryProperties file and tried using different solvers for ODESolver. But it didn't help. Can anyone help me on this?

Thanks.
