I am trying to simulate combustion in an internal combustion engine, but as I reach the ignition time I get the following messages in the .info file:

Hi all,
and especially roadracer.

I have read a lot of your posts, and I think I am doing smthg really similar to what you were doing six years ago.

And of course, I am facing exactly the same problems. Can you help me explaining how finally you solved the problem in this topic?

Thanks in advance...
