Hi everyone, <\/p>\n

I’m trying to simulate deformation due to thermal expansion in multilayered fire-resistant glasses. At the moment my model consists of two glass panes with an intumescent interlayer in the middle. (There is also a steel plate in the model, where the glass is lying on, which serves as a heat source via its body temperature)<\/p>\n

My workbench looks like this:<\/p>\n

<\/p>\n

And at the moment I calculate the thermal part first and after that I calculate the mechanical part. And as you can see, for now the simulation works, but there is still a big difference to real world experiments and thats why I want to couple the simulation step by step if this is possible.<\/p>\n

First, the expansion of the intumescent material is huge, it’s greater than 10x (1.4mm at the start, 14.8mm at the end of the experiment). Also, the material properties change with temperature. Finally, when I look at the end result of the the structural simulation, the edges of the glass lost contact (bent upwards) sometime during the heating process, but this wasn’t considered in the thermal analysis.<\/p>\n

For all these reasons, I want to couple the two systems step by step, so after the first thermal time step is completed I want to give the result to the structural system, then use the result (which is mainly the change geometry) as input for the next time step of the thermal system and so on.<\/p>\n

I also just watched this video: https:\/\/www.youtube.com\/watch?v=SHZKOYqJXkA but it seems, while there is a different way of connecting the 2 systems, the way shown in the video also does not allow a data transfer in both directions.<\/p>\n

I would be very happy if someone could help me, thank you!<\/p>\n","protected":false},"template":"","class_list":["post-311646","topic","type-topic","status-closed","hentry","topic-tag-heat","topic-tag-material-properties","topic-tag-mechanical"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["96.7.218.223"],"_bbp_subscription":["36261","13927"],"_wp_old_date":["2023-10-16"],"_btv_view_count":["2579"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["311646"],"_bbp_forum_id":["27791"],"_bbp_engagement":["13927","36261"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["311792"],"_bbp_last_active_id":["311792"],"_bbp_last_active_time":["2023-10-17 12:07:33"]},"test":"christian-neuertugraz-at"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/311646","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\/311646\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=311646"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
