If one of the pictures 1 or 2 is satisfied, will the element be deleted? Or do&nbsp; need to meet both criteria at the same time? Is the deletion of the element only related to the stress strength and ERODS entered in the material card? But ERODS is evaluated against a scalar strain computed from the two in-plane normal strains and the in-plane shear strain. Suppose I enter an ERODS of 0.5, will the unit be deleted when the ERODS value calculated by the formula in Figure 3 reaches 0.5?&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/05\/25-05-2025-1748185254-mceclip0.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/05\/25-05-2025-1748185282-mceclip1.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/05\/25-05-2025-1748185296-mceclip2.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-432505","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["291846"],"_bbp_topic_id":["432505"],"_bbp_author_ip":["64.181.248.35"],"_bbp_last_reply_id":["433365"],"_bbp_last_active_id":["433365"],"_bbp_last_active_time":["2025-06-05 05:59:05"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["342823","523"],"_btv_view_count":["633"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["523"]},"test":"1617836513qq-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/432505","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\/432505\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=432505"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
