Axial stretching

class AxialStretching(all_info, group)

The constructor of a stretching object of the box for a group of particles.

Parameters:

• all_info (AllInfo) – The system information.

• group (ParticleSet) – The group of particles.

setBoxLength(Variant vL, string direction)

specifies the change of box length and its direction with Variant. The candidates are “X”, “Y”, “Z”.

Example:

v = gala.VariantLinear()
v.setPoint(0, 31) # time step, box length.
v.setPoint(100000, 60)

axs = gala.AxialStretching(all_info, group)
axs.setBoxLength(v, 'Y')
app.add(axs)
