See the attached picture for reference. In this simple geometry, I want to refine the mesh about an arbitrary point on the top edge. In this application, the location is keypoint 7, but it could be anywhere on the top edge, including the corners. My ultimate goal is to have the refinement location sweep over the top edge, producing a sequence of meshes which I can use for my work. Since the location of refinement is not guaranteed to coincide with any node in the mesh, I thought to define the mesh refinement locus as a keypoint in the geometry and use KREFINE. However, as the picture demonstrates, this command fails. Even if I use the GUI to associate the keypoint with the line (modeling -&gt; create -&gt; keypoints -&gt; on Line w\/Ratio), and then use the GUI to refine at the keypoint (Meshing -&gt; Modify Mesh -&gt; Refine At -&gt; Keypoints), the command still fails. I&#039;m not sure what I&#039;m doing wrong. What do I have to associate with this keypoint so that I can refine the mesh at it? Am I approaching the problem incorrectly? My thanks for any clarification that can be provided!<\/p>\n<div class=\"embedExternal embedImage\">\n<div class=\"embedExternal-content\">\n<a class=\"embedImage-link\" href=\"\/forum\/wp-content\/uploads\/forum-uploads\/399\/8HRC6WDCPJS0.png\" rel=\"nofollow noopener\" target=\"_blank\"><br \/>\n<img decoding=\"async\" class=\"embedImage-img\" src=\"\/forum\/wp-content\/uploads\/forum-uploads\/399\/8HRC6WDCPJS0.png\" alt=\"invalid_keypoint_refinement.PNG\" \/><br \/>\n<\/a><\/p>\n","protected":false},"template":"","class_list":["post-163212","topic","type-topic","status-closed","hentry","topic-tag-keypoints-1","topic-tag-local-refinement-1","topic-tag-meshing"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello,I am trying to implement a moving mesh.
