I read your answers, but I think (it maybe wrong)  after density calculating 
 in each step of vc-rx calculations, the program should use it in the next 
step. so because of trivial changes in cell parameters the number of 
iterations should decrease in each step, shouldn't?
I have another question about introducing one layer to code. How could I 
select c parameter along z direction ,I mean how large it should be? Could I 
say if stress along z direction become zero after 2-3 steps  in  vc-rx  my 
selection is correct?
