My simulated eye is several cyinders with their respective materials, with a pupil in the iris which changes from 1mm radius to a 4mm radius. As the pupil increases in size there will be more conductive fluid and less muscle tissue (non-conductive) in the current path which should lower the resistance of the eye.&lt;\/p&gt;&lt;p&gt;When I apply a constant current of 100mA (which is high but its just for checking resistance). The rsuslts are as follows:&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/08-10-2024-1728415490-mceclip3.png\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/08-10-2024-1728415720-mceclip4.png\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/08-10-2024-1728415743-mceclip5.png\" \/>&lt;\/p&gt;&lt;p&gt;Would anyone have any idea how to change this simulation so that the results are less speratic of is there a better way to do this other than Maxwell 3D DC Conduction?&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-388665","topic","type-topic","status-publish","hentry","topic-tag-AnsysMaxwellelectronics-1","topic-tag-3d-maxwell-simulation","topic-tag-ansys-maxwell-3d"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["466623","82626"],"_bbp_author_ip":["128.187.112.17"],"_btv_view_count":["147"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["388665"],"_bbp_forum_id":["27793"],"_bbp_engagement":["82626","466623"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["389329"],"_bbp_last_active_id":["389329"],"_bbp_last_active_time":["2024-10-11 21:07:45"]},"test":"ethanwgbyu-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/388665","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\/388665\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=388665"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
