Hi NAMD users,
I am trying to equilibrate a solvated protein with
nearly 60 residues. I am using isothermal-isoberic
ensemble to equilibrate with periodic boundary
condition. At first, I calculated the box size using
TkConsole in VMD ( using the command measure minmax
and measure center ) and I used that to set up
cellBasisVectors and cellOrigin. After that, during
each restart I am passing xsc file saved from last
step for boxsize and boxorigin. I found that NAMD is
changing the box size slightly at each step which is
evident. Now do I need to also change the PMEGridSize
when the box size changes? Or can I keep thw samw
PMEGridSize as long as my cellBasisVectors are smaller
than PMEGridSize parameters?
Santanu
