About the effect of pulling velocity for the" fix smd" command

Dear all,
When I adopted the " fix smd" command for pulling one workpiece, which is connected to another workpiece by the van der Waals interaction.
I want to know if the different pulling velocity can influence the pulling force and the potential of mean force (PMF)?
thanks in advance,
Yancheng

yes. please see the paper referenced in the fix smd
documentation for a discussion of accuracy issues.
