Denis,
  set the max number of steps negative. It will remove the warnings. Best

Hi Rene,
Actually i do not want to increase the number of steps since it will slow down my simulation, is there another way ? Why the gMC-SetDEBU(0,0,0) does not work in this case ?

                      cheers,
                            Denis

Hi Denis,

Simply set MAXNST (in gctrack common) to a much larger value. It is set to 10000 in ginit
