Dear all
I am running a NAMD simulacion, but the program yield this message:

OPENING EXTENDED SYSTEM TRAJECTORY FILE
FATAL ERROR: Periodic cell has become too small for original patch grid!
Possible solutions are to restart from a recent checkpoint,
increase margin, or disable useFlexibleCell for liquid simulation.
