But I don&#8217;t know how this can be achieved in ROCKY.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/07-12-2024-1733609526-Wic.jpg\" alt=\"\" width=\"290\" height=\"149\" \/>&lt;\/p&gt;&lt;p&gt;Considering the above image Say particle A in my simulation. I wish to calculate the frictional slip work as particle A get in contact with its neigborhood. Then sum the frictional work for the entire simulation time. I consider my frictional slip work to be mu*normal force*displacement.&lt;\/p&gt;&lt;p&gt;However I dont know how to account for displacement in rocky. Any useful information to go about this calculations will be appreciated.&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Best regards,&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;Ayuk&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-396681","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["396681"],"_bbp_author_ip":["128.118.74.81"],"_bbp_last_reply_id":["397140"],"_bbp_last_active_id":["397140"],"_bbp_last_active_time":["2024-12-11 17:13:55"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["66412","66199"],"_btv_view_count":["229"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["66199"]},"test":"cma6301psu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396681","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/396681\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=396681"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
