[Polli]

Hello to all!
I have the folowing problem:
I simulate on OpenFOAM 2.2.2 an lagrance cloud which consists of ash, C, and C16H34 as a liquid. The evaporation i simulate with the liquid evapouration model. The simulation deals with particles which fly trough a hot gas and start to burn. The simulation runs perfect for the fist 10 000 interations but then i always get the following error message. I tried to reduce the timestep but this also not work. And one more strange thing, after the breakdown of the simulation, wenn i restart it from the last timestep i also get an error message. Below i poste the console output with the two last normal timesteps and the error message. After the error message i restartet the simulation and then there was the next error.

Thank you for your help, yours Polli
