Extract Radial Strain from Axial Deformation Process

Dear All,

I would like to extract the radial strain of a CNT subjected to axially applied force.

Would you please let me know the how to dump/thermo the output as Radial strain versus Axial deformation?

Best regards


You can use compute displace/atom to dump how far
each atom have moved since time 0, as a vector
displacement. You could then post-process the
dump file to determine radial strain. I suppose if you
were clever you could write a per-atom variable that

would calcluate that number for you and dump it as well.
