Upon running LMESH with this line selected, the application displays an error message which reads &#8220;The definition implied by the TSHAP command is improper for element 1. Please check the TSHAP command.&#8221; It seems this occurs because LMESH automatically sets TSHAP and TARGE170 elements do not have ARC or CARC as an option. LMESH does successfully complete with TARGE169 elements but this causes the elements to be generated on the X-Y plane, which is unacceptable. I have also tried splitting the line with LDIV but it seems each individual segment is also an arc and fails with LMESH. My desired result would be for LMESH to generate LINE or PARA shaped TARGE170 elements with the ability to use LESIZE to split the line into N segments. Is this possible? Are there any APDL commands which approximate the arc as a bspline?<\/p>\n","protected":false},"template":"","class_list":["post-250905","topic","type-topic","status-closed","hentry","topic-tag-apdl"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"I am running into an issue meshing a line using LMESH with TARGE170 elements.The line is imported from a Parasolid file and happens to be a circular arc in three dimensional space.
