For a 1×1 planar element with all nodes selected, I get ARNODE values of 1.0 for each node. I was expecting 0.25."},"content":{"rendered":"

ARNODE is documented to return the edge area for 2-D planar elements. In this case, that was 1.0. If you had selected the nodes on one face of the 1×1 element it would return 0.5. Possible ways to get the true area of a 2-D element are to use the GET function ARFACE(e) divided by the number of nodes selected or by temporarily converting the elements to 3D shells, doing the ARNODE(n), and then converting the elements back to 2D.<\/p>\n","protected":false},"template":"","class_list":["post-165251","topic","type-topic","status-publish","hentry","topic-tag-4653","topic-tag-general","topic-tag-mechanical-apdl-f-ansys","topic-tag-structural-mechanics"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
