Jan Stránský proposed the following answer:
Hello,
> But I don't know how to measure the volume change.
dV = refVolume - O.cell.volume # [1], absolute value
or
dV = 1.0 - O.cell.trsf.determinant() # O.cell.trsf is deformation gradient,
google e.g. "deformation gradient volume change", in range [0,1]
> I can not keep the boundary's shape (I want to keep it in as a flat at
each surface).
Please be more specific.
In fact, as the simulation is periodic, there is no "boundary" or "surface"..
cheers
Jan
