Hi Shirin,

The message which you reported can happen due to overlaps in a geometry description or to the navigator becoming confused at the boundary between volumes.

It seems that you are creating a geometry with many very small volumes.  Is this the case ? 

Could you describe a bit more about your setup, and whether you have an EM field ?   ( Please do not give tens of lines of code - a description is better at this stage.)

Regards,
John
