Hi Edward, Jeyasingam,

I'm terribly sorry for the late answer but somehow I managed to miss your thread.

I believe the problem you reported has been fixed in the latest version of INCL++ (v5.1.14), which will be distributed with the coming Geant4 release (v10.0) (beginning of December). I encourage you to upgrade your Geant4 installation as soon as the release is out. The latest INCL++ is much more stable than the older versions.

Please note also that the INCL_ABLA physics list is not available any more. You will still be able to couple ABLA to INCL++, though (the technique will be explained in the Application Developer Guide).

Also, four INCL++-based stock physics lists will be available in Geant4 v10.0. These are:
* QGSP_INCLXX
* QGSP_INCLXX_HP
* FTFP_INCLXX
* FTFP_INCLXX_HP
As you can guess, the *_HP variants use NeutronHP at low energies.

Regards,
Davide
