[gmx-users] Avoiding calculation on some degrees of freedom

Dear Gromacs Users,

is there any way in Gromacs
to keep some bond lenghts or angles fixed,
avoiding calculation of forces from them?

For example, if atoms A and B are bonded, and some force
acts on A, I want to keep the A-B distance constant, moving B
as much as A, and B not affecting force on A.

Thanks,
