But about 3V bias is needed for operation. I have employed all of the methods mentioned in the website to ensure convergence such as finer mesh, initialization, gradient mixing, increasing iteration, update limiting, smaller voltage steps etc. But the simulation still produces convergence errors. So I would really appreciate it if anyone points out the things I should look for.&lt;\/span&gt;&lt;\/p&gt;&lt;p&gt;&lt;span style=&#8221;font-size: 8pt;&#8221;&gt;Thank you&lt;\/span&gt;&lt;\/p&gt;&lt;\/p&gt;&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-380932","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["37.111.210.230"],"_btv_view_count":["192"],"_bbp_topic_status":["unanswered"],"_edit_last":["343727"],"_bbp_revision_log":["a:2:{i:380933;a:2:{s:6:\"author\";i:343727;s:6:\"reason\";s:0:\"\";}i:380934;a:2:{s:6:\"author\";i:343727;s:6:\"reason\";s:0:\"\";}}"],"_bbp_subscription":["2592","343727"],"_bbp_topic_id":["380932"],"_bbp_forum_id":["27833"],"_bbp_engagement":["2592","343727"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["381094"],"_bbp_last_active_id":["381094"],"_bbp_last_active_time":["2024-08-29 16:00:53"]},"test":"niloy-2019118369eee-du-ac-bd"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/380932","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":2,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/380932\/revisions"}],"predecessor-version":[{"id":380934,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/380932\/revisions\/380934"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=380932"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
