[gmx-users] Free energy change with harmonic restraints

[asaffarhi at post.tau.ac.il]

Dear Natalie,

You have in

http://xxx.tau.ac.il/pdf/1502.07196v3.pdf

exact free energy of harmonic covalent bond and bond angle terms (or  
restrains). See Eqs. (2) and (3).

There are also previous studies in the references there.

For the dihedral term I assume it can also be calculated exactly (I  
might upload it).

There is also to think if there are other contributions.

If you are using it please cite.

Best regards,
Asaf
