hi,everyone,i am a new openfoam user. I am running the sprayFoam case, where i implement the specie C12H26. I have changed the chem.inp and therm.dat. But when the case runs a few steps, it cracks. It stopped at 0.00151s.The error is like below:

Courant Number mean: 3.71158e-05 max: 0.0695979
deltaT = 1.25e-06
Time = 0.001515

Is there anybody who can help me? I guess it should be caused by particle or parcel parameters set in spraycloudProperties file, so I attached it. It can be open by word.
Thanks !
