Dear Gromacs Users I have set my pull option as "constant force" and the pull geometry is "distance" the manual has stated that the pull_k1 unit is kJ/mol/nm . does it mean that the force applied to the protein is proportional to the distance between the 2 groups ? else what is it ?
my second question is that what is the preferable choice for the pull ref group (pull_group0) in a protein when the force is exerted to the first and last res of the molecule . Best Regards Ali
