As I understand it, the results are evaluated at the Gauss integration points, then interpolated at the corner nodes. The mid-side nodes are the average of the two corner nodes. When I probe, the result is there, but when I export, usually the corner node results are correct, and the mid-side nodes are empty.&lt;br&gt;&lt;br&gt;I have tried using AVRES, 1 and ERESX, YES, as well as PRNSOL, S, EQV&lt;br&gt;&lt;br&gt;The code has this base:&lt;br&gt;&lt;br&gt;\/POST1&lt;br&gt;SET, LAST&lt;br&gt;ALLSEL, ALL&lt;br&gt;\/GRAPHICS, POWER&lt;br&gt;\/EFACET, 2&lt;br&gt;AVRES, 1&lt;br&gt;AVPRIN, 0, 1&lt;br&gt;ERESX, YES&lt;br&gt;CMSEL, S, Nodes&lt;br&gt;*GET, n_count, NODE, 0, COUNT&lt;br&gt;&lt;br&gt;&lt;\/p&gt;&lt;div&gt;*DIM, node_ids, ARRAY, n_count&lt;\/div&gt;&lt;div&gt;*DIM, vm_stress, ARRAY, n_count&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;curr_node = 0&lt;\/div&gt;&lt;div&gt;*DO, i, 1, n_count&lt;\/div&gt;&lt;div&gt;&nbsp; &nbsp; curr_node = NDNEXT(curr_node)&lt;\/div&gt;&lt;div&gt;&nbsp; &nbsp; node_ids(i) = curr_node&lt;\/div&gt;&lt;div&gt;&nbsp; &nbsp; *GET, vm_stress(i), NODE, curr_node, S, EQV&lt;\/div&gt;&lt;div&gt;*ENDDO&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;I have tried a few different approaches, but I never manage to export the values at the mid-side nodes, which I know exist due to the probe tool returning me results. I wanted to avoid having to &#8220;manually&#8221; calculate the average between two corner nodes. Does anyone know if it&#8217;s actually possible, and if so, how to export these results? Otherwise I think I might just use only corner nodes instead.&nbsp;&lt;br&gt;&lt;br&gt;Thanks for reading&lt;\/div&gt;<\/p>\n","protected":false},"template":"","class_list":["post-456662","topic","type-topic","status-publish","hentry","topic-tag-ansys-apdl","topic-tag-ansys-mechanical-apdl","topic-tag-export-result","topic-tag-exporting-data-1","topic-tag-mesh-nodes","topic-tag-nodes-problem-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["456662"],"_bbp_subscription":["343288"],"_bbp_author_ip":["2804:7f4:c013:a540:816:2c66:f4d4:afbe"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["456662"],"_bbp_last_active_time":["2026-04-18 22:19:23"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["1"],"_bbp_engagement":["343288"],"_btv_view_count":["8"],"_bbp_topic_status":["unanswered"]},"test":"mikaelgmrsgmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/456662","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\/456662\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=456662"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
