Title: Regarding Wiegner Seit modifier
Post by: bahmanpbamp on June 07, 2019, 05:11:32 PM
Dear OVITO expert(s),

In the Wigner-Seitz defect analysis explanation on OVITO website, it has been explained that in dynamic cases it is possible to eliminate the homogeneous cell deformation. But I cannot find clearly any relevant key in the modifier which apply this criteria to the modifier. I am using OVITO version 3.0.0 already.  Actually I did not clearly understand what "affine mapping of the simulation" kye in the modifier of version 3.0.0 is and I could not also find it in the documentation.

So any help is highly appreciated.


Best regards,
Bahman

Dear Bahman,

I am wondering: Did you already read the section "Affine mapping of the simulation cell" on the documentation page of the WS modifier? It can be found here:

http://ovito.org/manual_testing/particles.modifiers.wigner_seitz_analysis.html

This section explains the purpose (and naming in the UI) of the modifier option controlling the mapping of the deformed simulation cell back to the undeformed geometry.

Dear Alex,

Thank you very much for your response. Actually it is amazing, the link that you sent to me is different from what I have seen! you can see this link

By the way, now everything is clear! thanks a lot

Dear Bahman,

the difference is that you are referring to the OVITO 2.9 manual, whereas ovito.org/manual_testing (http://ovito.org/manual_testing/) is the manual of the latest developer version.
You'll see this if you follow the links to the documentation of the respective OVITO versions on the download page.
