I&#8217;m assessing a bone in a 4 point bending test and I&#8217;ve applied a displacement\u00a0to 2 cylinders above the bone (attached). For the sake of this explanation, let&#8217;s say I applied a total displacement of 5mm. So as far as I&#8217;m aware:<\/p>\n<ul>\n<li>The initial substeps is the starting point of the analysis, so an initial substep of 5 means it will began the calculations from 5mm\/5 = 1mm<\/li>\n<li>The minimum substep is the minimum number of steps for which the displacement\u00a0will increase over, so a min substep of 4 will mean the programme will increase the displacement by a max of 5mm\/4 = 1.25mm<\/li>\n<li>The maximum substep is the maximum number of steps for which the displacement will increase over, so a max substep of 20 will means the programme will increase the displacement by a max of 5mm\/20 = 0.25mm<\/li>\n<\/ul>\n<p>The programme will begin at the displacement of 1mm and initially increase the displacement in jumps of 1.25mm. If the results can&#8217;t converge, it will increase the substep to 5 and do it again in jumps of 5mm\/5 = 1mm. If it can&#8217;t converge again it will increase the substep to 6 and do jumps of 5mm\/6 = 0.83mm and so on.<\/p>\n<p>Am I on the right lines or am I way off?<\/p>\n<p>Appreciate anyone&#8217;s help!<br \/>\n<a style=\"float: left;width: 245px;\" to=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/VL856AQTM1WU\/screenshot-2020-12-23-121352.jpg\" class=\"attachment-link_f1y095ym attachment-box_fehgzty\" type=\"image\/jpeg\" download=\"Screenshot 2020-12-23 121352.jpg\" tabindex=\"1\" href=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/VL856AQTM1WU\/screenshot-2020-12-23-121352.jpg\"><\/p>\n<div class=\"attachment-format_f1pihadh\"><svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 16 16\" class=\"attachmentIcon-fileImage attachmentIcon iconSizes-fileType_f1ixov3b attachmentIcon_fmnn8ng\" role=\"img\" aria-label=\"An image file\"><title>Image<\/title><rect width=\"16\" height=\"16\" rx=\"1\" style=\"fill: rgb(200, 0, 144);\"><\/rect><path d=\"M3,12.5a1,1,0,0,1-1-1V6A1,1,0,0,1,3,5h.5V4.75a.25.25,0,0,1,.25-.25h.5a.25.25,0,0,1,.25.25V5a.81.81,0,0,0,.724-.447l.5-1A1,1,0,0,1,6.618,3H9.382a1,1,0,0,1,.894.553l.448.894A1,1,0,0,0,11.618,5H13a1,1,0,0,1,1,1v5.5a1,1,0,0,1-1,1Zm5-2a2,2,0,1,1,2-2A2,2,0,0,1,8,10.5Zm0,1a3,3,0,1,0-3-3A3,3,0,0,0,8,11.5ZM11.5,6V7H13V6Z\" style=\"fill: rgb(255, 255, 255); fill-opacity: 0.97;\"><\/path><\/svg><\/div>\n<div class=\"attachment-main_fwqa6oh\">\n<div class=\"attachment-title_fz0ytih\">Screenshot 2020-12-23 121352.jpg<\/div>\n<div class=\"attachment-metas_fmtzr8l metas_f1bfxqm4\"><span class=\"metas-meta_fb6825\">36.84<abbr title=\"Kilobyte\"> KB<\/abbr><\/span><\/div>\n<\/div>\n<p><\/a><\/p>\n","protected":false},"template":"","class_list":["post-50825","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["23078"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":["*\u0000#?Q?\u0013\u0001??w??C?O"],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["5413"],"_edit_lock":["1660196984:76739"],"_edit_last":["76739"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["50825"],"_bbp_forum_id":["27791"],"_bbp_engagement":["490","184458"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["137286"],"_bbp_last_active_id":["137286"],"_bbp_last_active_time":["2020-12-31 23:34:55"]},"test":"milesvivian"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/50825","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\/50825\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=50825"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
