[Pw_forum] error in stress calculation

[Raghani Pushpa]

Dear users,
I am getting the following error while calculating stress in Au/Ag system 
in a slab calculation.

     entering subroutine stress ...
 
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     from sph_bes : error #         2
     j_{-1}(0) ?!?
 
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
     stopping ...
2

whereas the code works well for ag/pt (slab) system.

what could be the problem?
