The geometry is basically a prism, which would be the electrolyte, with an electrode on each side (for cathode and anode). It also has an inlet and outlet in the top and bottom sides. I want to have the anodic reaction (2 H2O -&gt; O2 + 4H+) on the surface with the anode and the cathodic reaction (2 H+ -&gt; H2) on the other surface. I&#039;ve tried to follow the user&#039;s guide and what it says, but once I calculate the simulation, there doesn&#039;t appear to be any reaction. The pressure and velocity contour graphics show that there is flow of material, but there&#039;s no reaction heat nor reaction rate. I&#039;ve tried the same model but with the volumetric reaction and everything works, but when I do it with the electrochemical model, there&#039;s no reaction.<\/p>\n<p>Maybe someone has had the same problem or knows any common mistake when doing this kind of reaction.<\/p>\n<p>Thanks for your help.<\/p>\n","protected":false},"template":"","class_list":["post-167700","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["1345"],"_bbp_likes_count":["0"],"_bbp_subscription":["251951","270629"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["167700"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","7737","251951","270629"],"_bbp_voice_count":["4"],"_bbp_reply_count":["11"],"_bbp_last_reply_id":["311749"],"_bbp_last_active_id":["311749"],"_bbp_last_active_time":["2023-10-17 05:24:33"]},"test":"ydominguezirec-cat"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/167700","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\/167700\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=167700"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
