Hello,
Try the following settings (usually applied to membrane simulations, don't
know if they suit you unless you tell us more about your system):
useFlexibleCell yes ;# (permits anisotropic fluctuations during pressure
control)
useConstantRatio yes ;#(The X-Y ratio remains constant, while the Z-axis
is left free to fluctuate)
useConstantArea no ;# (When constant ratio is set to yes, Constant Area
must be No)
And of course, the manual is your friend. Use it:
