Hi OF community

I simulated a flame with reactingfoam in serial and had no problems in a 5 second5 simulation . But when running the same in parallel it quits at 0.08 and displays the following error message.

I must say that is the first run in parallel i try, so i ask for patience

any comment is strongly appreciated.

thanks
V
