The frcmod file for ff99SBildn is present in dat folder.
The path is *amber18/dat/leap/parm *and the file is frcmod.ff99SBildn.
In amber18 while using tleap, it is giving some error while using
ff99SBildn force field
>tleap
>source leaprc.ff99SBildn
Error
This is because leaprc.ff99SBildn file is present in
amber18/dat/leap/cmd/oldff but while entering in tleap it includes the path
till amber18/dat/leap/lib.
So, you just need to *copy the leaprc.ff99SBildn file from
amber18/dat/leap/cmd/oldff to amber18/dat/leap/cmd.*
Then you will will be able to use leaprc.ff99SBildn in tleap.
For more clarification, I am attaching the screenshots.
