Description corneliu 2004-02-27 04:08:18 CET 
Hi,
 I am running a simulation of ion transport in thick targets using the binary
cascade model. The warning below occurs numerous times during a simulation (21
to be precise). The simulation then hangs and no further hits to the sensitive
volume are tallied.

G4RKPropagation::FieldTransport() warning: integration error.
position (-2.46673e-12,-1.77505e-12,3.86225e-13) 4mom
(3.08996,12.0564,-8.71199;938.395)
 timestep 5.84104e-13

Cheers,
Iwan

Hi Gunter,

 this is field transport in binary cascade. Can ou have a look?

Many greetings,

Hans-Peter.

This printing of an integration error is a warning only, and can be ignored. I
will disable this warning for future releases.

The "hang" is unrelated; do you have any information where this occurs? Can you
run this in the debugger, and when its "hanging" interrupt the program, and
print a traceback using where?
Or can you make your source available?

Gunter
