I am confused when im doing unixial tension using the fix deform
command. I cannot understand the parameter N very clearly, although it
has been explained in the doc. Every Nth timestep during the run, the
simulation box is expanded, contracted, or tilted to ramped values
between the initial and final values. Does the 'ramped values'
generally depend on the total timesteps of the run?
fix 1 all deform 1000 z scale 1.3
Will the 1.3 be divided 10 (10000/1000=10) times during the run?
For another example, use erate style
fix 3 all deform 1000 z erate 0.00015
1. What is the meaning of 1000 in the above fix deform command? Does
it mean a 0.00015 strain rate will applied to the box every 1000
timesteps? Can the 1000 be considered the box will be relaxed 1000
2. Does it have to do with the calculation of the engineering strain?
what is the strain after 100000 steps?
Many thanks for any advice.
