[gmx-users] Umbrella sampling windows

I'm running umbrella sampling of an ion through a lipid bilayer with gromacs
I used g_wham to create the histograms of the configurations within the
umbrella sampling windows (1 Angstrom interval).
I did not get a sufficient overlap between the windows, so I was wodering
which is the better way of increasing the sampling: to
include additional windows in the regions where there is no overlap or to
increase the force constant ?
If I increase the force constant can I continue the simulation with the new
constant or do I have to start again?
I used a force contant of 3000 kJ mol^-1 nm^-2.
Thank you in advance,
