  Invalid node/element number= 0. The BFE command is ignored.
  
  I am getting such an error. how can i solve it?
  
  I'm doing thermal analysis. This is the code I use.

  time_steps=time_weld/time_inc

  DO,jj,EMIN,EMAX,1
  X=CENTRX(jj)
  Y=CENTRY(jj)
  Z=CENTRZ(jj)
  CSI=Z+(VEL*(TAU-WTIME))

  Q=Q0*exp((-3)*(X**2+CSI**2)/(r0)**2)

  Hi Hasan,
  The error looks due to an element with the number '0' exists in the model. Try starting jj from 1 or set jj=1.
