I am working with PyMAPDL. Basically, some concrete parts are connected by slip-resistant shear joints.&lt;\/p&gt;&lt;p&gt;The tricky part about this is that each part is generated at a discrete time-step with varying geometry and material properties. This information is not known prior of a specific time step. The basic assembly of geometry already works out. But now my questions: How can i simulate stresses, strains and deformations properly at each time step? How can i use the results from a previous time step in the current one? How can i just add elements to the mesh without changing the already existinmg mesh?&lt;\/p&gt;&lt;p&gt;Correct me if i am wrong but in my opinion Birth and death technique should not work out since i don&#8217;t have a final model that is known in advance. I know of the command INISTATE but here I am lacking on some theoretical knowledge how to superimpose stresses and strains correctly.&lt;\/p&gt;&lt;p&gt;I would be very grateful for any advice or literature.&nbsp;&lt;\/p&gt;&lt;p&gt;Thank you in advance!&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-393716","topic","type-topic","status-publish","hentry","topic-tag-adaptivemesh-2","topic-tag-2d-modelling-1","topic-tag-apdl","topic-tag-mechanical","topic-tag-mesh","topic-tag-sequencialmodelling-1","topic-tag-sequential"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["481304","20905"],"_bbp_author_ip":["134.147.22.21"],"_btv_view_count":["238"],"_bbp_topic_status":["unanswered"],"_edit_last":["481304"],"_bbp_revision_log":["a:1:{i:393719;a:2:{s:6:\"author\";i:481304;s:6:\"reason\";s:0:\"\";}}"],"_bbp_topic_id":["393716"],"_bbp_forum_id":["27791"],"_bbp_engagement":["481304","20905"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["404276"],"_bbp_last_active_id":["404276"],"_bbp_last_active_time":["2025-01-09 15:04:32"]},"test":"07072f7acd85d8d0e44dfdaa58740b0aea0cec25"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/393716","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/393716\/revisions"}],"predecessor-version":[{"id":393719,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/393716\/revisions\/393719"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=393716"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
