So I have entered the alpha &amp; beta values for the 2 rope materials in Engineering Data. When I set the Damping to be &#8220;on&#8221; in Analysis Settings, it shows Constant Structural Damping Coefficient, Stiffness Coefficient and Mass Coefficient (Attached screenshot). What should I enter here so that the material damping values are the primary drivers?<\/p>\n<p><\/p>\n<p>Note: Only the ropes have material damping values. No damping values have been set for steel (the rest of the model).<\/p>\n<p><\/p>\n<p>Any tips and advices would be great.<\/p>\n<p><\/p>\n<p>Cheers.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/7cd687c5-278a-4caa-8125-aa49007555c1\/2c7ecbdf-f34d-40f2-a7c5-ab1700521d17_capture.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-39318","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["11497"],"_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"],"_btv_view_count":["3500"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["39318"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","165202"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["99701"],"_bbp_last_active_id":["99701"],"_bbp_last_active_time":["2019-12-02 12:05:20"]},"test":"whiew"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/39318","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\/39318\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=39318"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
