The values are deviating a lot. Initally I started with program controlled and then when I was geting huge spikes in the curve I then switched to iterative solver. I have tried to reduce the timestep but still the curve is all spiky.<\/p>\n<p>So what can I do to optimise the time step for my problem so that I can get a convergent graph.&nbsp;<\/p>\n<p>Also is there a way to check simultaneously that the solution is converging or not like it could be seen in ANSYS Fluent with curves continously plotting.&nbsp;<\/p>\n<p>I am attaching a few pictures of the settings and APDL Commands that I am giving for refernce.<\/p>\n<p><img decoding=\"async\" title=\"Analysis setting 1\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/01-03-2024-1709289560-Screenshot 2024-03-01 160024.png\" alt=\"\"><img decoding=\"async\" title=\"Analysis setting 2\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/01-03-2024-1709289519-Screenshot 2024-03-01 155944.png\" alt=\"\"><img decoding=\"async\" title=\"APDL Commands\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/01-03-2024-1709289233-Screenshot 2024-03-01 155844.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/03\/01-03-2024-1709289135-Screenshot 2024-03-01 160130.png\" alt=\"\"><\/p>\n<p>#ansysmechanicalapdl #ansysmechanical #transientthermal #thermalanalysis #gaussianheatsource<\/p>\n","protected":false},"template":"","class_list":["post-354776","topic","type-topic","status-closed","hentry","topic-tag-ansys-mechanical","topic-tag-ansys-mechanical-apdl","topic-tag-ansys-transient-thermal-2","topic-tag-gaussian-heat-source","topic-tag-transient-thermal"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["302550","20905"],"_bbp_author_ip":["23.52.43.81"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2747"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["354776"],"_bbp_forum_id":["27791"],"_bbp_engagement":["20905","302550"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["355661"],"_bbp_last_active_id":["355661"],"_bbp_last_active_time":["2024-03-06 15:02:44"]},"test":"shivansh-karanwal-mec20itbhu-ac-in"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/354776","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\/354776\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=354776"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
