hey Bishal..
Go to  ~/siesta/Util/vibra/src  and modify in the  line no. 22  in vibra.h   
parameter (maxa = 8)  to parameter (maxa = 64) and recompile fcbuild and 
vibrator  simply using   make. 

I think this will work.

all the best.

Nick Papior Andersen,

Thanks for your earlier Reply.

I did the following steps till now,




(compile siesta)

cd Obj
sh ../Src/obj_setup.sh

cd ../Pseudo/atom
make
cd ../../Util
sh build_all.sh

This this generated both executable file for the 
fcbuild.f & vibrator.f in the Util/Vibra/Src package. Now the 
description says that it will use a .fdf file as an input and it creates
 an .fdf file as an output. Is this the same fdf file used during the 
run of siesta or is it from my output files or i have to have a new 
input file ?? 

I also tried.

fcbuild < sih.fdf (my initial input file )

it gives the error as 
redata:
 System Name                      = SIH1 
                                                                                
            
redata: System Label                     = SIH1
Number of Atoms                  =   64

chkdim: ERROR: In fcbuild, dimension maxa =       8. It must be at least      64


 

i have already generated a .FC file for the phonon relaxation. I am doing it in 
the siesta 3.1 version.



EVERY BIT of information and Suggestion will be fully appreciated. Thankyou.
