Hi,

   thank you for reporting this. It is a tricky thing to debug, though, since
the evaporation code is used by many models, and the error lies in the
preparation of the fragment. Can you 'break G4Exception' in the debugger, and
send me a stack trace? Alternatively: can you make your source code available,
then we can reproduce the fault directly, and the fix should be fast.

Many greetings,

Hans-Peter.

Hi,

   I just realized that you did not come back on this since my last mail. Are
you able to give more information on how the fault occures?

Many greetings,

Hans-Peter.

Hi,

  sorry that I keep bugging you on this, but I really would like to fix it.
Can you please help me out. As is I cannot make progress.

Many greetings,

Hans-Peter.

Hi,

  it turns out, that this can happen with the example -N04 physics list. The
'educated guess' physics lists will solve the problem.

Many greetings,

Hans-Peter.
