The subroutines "politr and pol2der" are called in forces.f which
probably may be computing the derivatives but I cannot find the
detailed programs themselves. Below is the section I found in the
forces.f
if(ipol.ne.0) then
! subroutine politr(natom,nres,c,q,pol,ipair,jpair,
! - eold,enew,eper,epol,xwij,r2,ipres,
! - aveper,aveind,avetot,emtot,nstep,
! - iptsol,n14,ni14,iarx,jpw,imgslt
! - ,iptatm,scr1,scr2)
!
call politr(natom,nres,x(mx),x(mchrg),x(mpol),ix(miar1),
- ix(miar2),
- scr1,enew,scr3,epol,scr4,scr5,ix(mipres),
- aveper,aveind,avetot,emtot,nstep,
- iptsol,n14,ni14,iscr1,iscr2,imgslt,
- iptatm,scr7,scr8)
lim = 3*natom*(3*natom-1)/2
do jn=1,lim
scr2(jn) = 0.d0
enddo
!
! subroutine pol2der(natom,x,f,p,q,h,ipair,
! - jpair,xrc,xij,r2,fw,vt,
! - n14,ni14,iarx,jpw,imgslt,iptatm,ndrv)
!
call pol2der (natom,x(mx),x(mf),enew,x(mchrg),x(mh),
- ix(miar1),ix(miar2),scr1,scr3,scr4,scr5,vt,
- n14,ni14,iscr1,iscr3,imgslt,iptatm,ndrv)
endif
If these compute the derivatives then please direct me to the program
files.
Thanks.
