I am using Fluent and Transient Structural for the coupling. The biological material is modeled as a hyperelastic Ogden material up to the failure point (failure point is the maximum stress). I was a able to successfully run the FSI simulation with the Ogden constants. Now I am trying to add damage modeling to the biological material as well. I know it is possible to combine linear elastic with damage. However, I am having problems with using a hyperelastic model with damage. I get an error that says &#8220;<em>More than one material option has been defined for material 1. Hyperelastic material (TB,HYPER) is not supported with other nonlinear&nbsp;material models.<\/em>&#8221; I haven&#8217;t had any luck looking online; is it possible to combination hyperelastic modeling with damage in ANSYS?<\/p>\n<p><\/p>\n<p>Thank you for your time and help.<\/p>\n","protected":false},"template":"","class_list":["post-32915","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["5087"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["731"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["32915"],"_bbp_forum_id":["27791"],"_bbp_engagement":["157908","160648","162051"],"_bbp_voice_count":["3"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["76795"],"_bbp_last_active_id":["76795"],"_bbp_last_active_time":["2019-02-04 17:14:52"]},"test":"sallyuidaho"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/32915","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\/32915\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=32915"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
