Jan Stránský proposed the following answer: Hello, as (almost) always, a MWE [1] would be useful (e.g. to know what "particle" is - sphere, polyhedra...), expressing on a few artificially created spheres and artificially created interactions to show what you want to achieve and what is your expectation of "anisotropy of contact normal vector", etc. Often you could solve your problem just by preparing such MWE. Furthermore, it will help us to help you :-) > how to calculate the contact normal vector for i in O.interactions: contactNormalVector = i.geom.normal # [2] > i want to know how to calculate anisotropy of contact normal vector if I understand it correctly, fabric tensor (as suggested by Bruno) is what you are looking for [3] cheers Jan [1] https://www.yade-dem.org/wiki/Howtoask [2] https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.GenericSpheresContact.normal [3] https://yade-dem.org/doc/yade.utils.html#yade._utils.fabricTensor -- You received this question notification because your team yade-users is an answer contact for Yade. _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
