The way I&#8217;ve tested it is creating a mesh, doing the geometry, adding convection, setting material as nickel and such, then putting 50A of current to each of the 3 links individually, and then 0V to the other 3 terminals. I ran into a problem where the full current is being dumped into the first ground terminal instead of being equipotential. I am trying to simulate 3P cells&#8217; positive terminals discharging in series with another 3P cells&#8217; negative terminals. How do I simulate this without having it dump all 150A into the first terminal and having a very skewed temperature reading? I have done everything correctly on the mechanical side I believe as I reached out to a mechanical engineer who was pretty good at ansys, I am stuck on the electrical portion as I have no idea how to make it realistic discharge instead of causing it all to go into one terminal.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/08\/18-08-2025-1755531687-IMG_8225.jpeg\" alt=\"\" width=\"198\" height=\"554\" \/>&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2025\/08\/18-08-2025-1755531662-IMG_8226.jpeg\" alt=\"\" width=\"1222\" height=\"699\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-439553","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27786"],"_bbp_topic_id":["439553"],"_bbp_subscription":["585766","20905","170445"],"_bbp_author_ip":["192.58.125.2"],"_bbp_last_reply_id":["439670"],"_bbp_last_active_id":["439670"],"_bbp_last_active_time":["2025-08-19 21:20:48"],"_bbp_reply_count":["7"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["3"],"_bbp_engagement":["585766","20905","170445"],"_btv_view_count":["6224"],"_bbp_topic_status":["unanswered"]},"test":"oelgarhyttu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/439553","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\/439553\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=439553"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
