Hongyang Alex Cheng is still having a problem:
Hi, Bruno

the concept of "closest neighbours" would be undefined.

Thanks. Now I know how the TW, MMA and KLA work.

>Since you can read it (as in the line above), you can also write it
into a file. Is that what you mean by "save"?

I would like to compute the macro deviatoric strain. The function
KLA.computeParticlesDeformation() [1] returns 'ParticleDeformation' but
only ouputs 'Total volume ', 'grad_u', and 'sym_grad_u' on the screen.
If it is saved in memory can you tell me how to get it?
