Signal 11 when exhaust valve just closes
 
Hello,

I am running a 4 stroke engine model in STARCD/es-ice and the model runs with no issues up until the event corresponding to exhaust valve closing. The calculation then abruptly stops and displays Signal 11 - Exiting now.

The run was looking OK with no errors/warnings, even though the valve lift was very small, I had a small enough time step to deal with the high speed flow in the valve gap. The calculation just stopped without any other information apart from the signal 11 error.

Has anybody seen this before?

Thanks
Peter
