Respected Sir,

Many thanks for your valuable guidance.  According to your suggestions I have made the changes "runsp_lapw" and then run the SCF and it completed successfully.

But when I run the calculations for elastic constant and after successfully run init_elast and elast_setup when I made the changes in ./eos.job (runsp_lapw -ec 0.0001  -cc 0.0001 -NI) and then run the same script it again shows the following error 

[gga at phy-server elast]$ ./eos.job
eos___0.0
DSTART ENDS
1.446u 0.010s 0:01.45 100.0%    0+0k 0+0io 0pf+0w
 LAPW0 END
 LAPW1 END

>   stop error
ERROR status in eos___0.0

and in the error file (lapw1.error), the same error is reported

'INILPW' - can't open unit: 18                                                
 'INILPW' -        filename: eos.vsp                                           
 'INILPW' -          status: old          form: formatted                      
 'LAPW1' - INILPW aborted unsuccessfully. 
 
Kindly guide me.

Please remove all error files:    rm *.error

Then do a spin-polarized scf:     runsp_lapw

I'm pretty sure you first started      run_lapw; which of course crashed because
you have done a spin-polarized initialization (which produces case.vspup/dn, but not case.vsp).

A spin-polarized scf never accesses case.vsp.
