However, the soil particles are cohesive in nature and therefore I have to use the bond model module which I have used but I am wondering the best way to calibrate these bond model parameters (Tangential stiffness per area, Normal stiffness per area, shear stress limit and tensile stress limit)so that I achieve the exact cohesion of my soil so that when I run a one-way or two-way coupled simulation, it simulates the exact experimental result. Any advice on this? Any reading material that could help? <img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/09\/05-09-2025-1757063599-Internal erosion image.png\" alt=\"\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-440845","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["440845"],"_bbp_subscription":["518822","66199"],"_bbp_author_ip":["194.80.232.23"],"_bbp_last_reply_id":["441371"],"_bbp_last_active_id":["441371"],"_bbp_last_active_time":["2025-09-12 14:18:42"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["518822","66199"],"_btv_view_count":["11027"],"_bbp_topic_status":["unanswered"]},"test":"cnmatuleeds-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/440845","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\/440845\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=440845"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
