I already made all the contact (bonded and friction) and body interaction among my parts (solid and shells) and I have some penetrations between some of them (mostly ocurred because of the mesh between 2 cilindrical shells, the CAD offset is 0 and the offset type is correct, but the mesh is not perfectly cylindrical and i don&#8217;t need more precision there.<\/p>\n<p>I want to check the Penetration and Initial information in Contact tool, but i received an error: &#8220;An error ocurred inside the solver module: general error&#8221;\u00a0 in initial deformation. I dont understand why that happened because i can run the whole model in solution without this problem. Any help or advice for that? I would like to review the status of my contacts.<\/p>\n<p>On another hand, comming back to the penetration problem I said, I would like to use Ignore=1 to avoid the initial penetration caused by the mesh in my contacts. How could I active this parameter in Workbench? I tried to use Keyword Snippet but it caused a solver error and the model doesn&#8217;t run.<\/p>\n<p>I&#8217;m using Workbench 2026 R1.<\/p>\n<p>Thanks in advance,<\/p>\n<p>Marcos.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"font-size: 18.4px\" src=\"https:\/\/innomid.ansys.com\/forum\/api\/v1\/forum-file?file=\/forum\/wp-content\/uploads\/sites\/2\/2026\/08\/Captura-de-pantalla-2026-08-26-142941.png&amp;type=ext\" alt=\"\" width=\"736\" height=\"36\"><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innomid.ansys.com\/forum\/api\/v1\/forum-file?file=\/forum\/wp-content\/uploads\/sites\/2\/2026\/08\/Captura-de-pantalla-2026-08-26-143243.png&amp;type=ext\" alt=\"\" width=\"350\" height=\"206\"><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innomid.ansys.com\/forum\/api\/v1\/forum-file?file=\/forum\/wp-content\/uploads\/sites\/2\/2026\/08\/Captura-de-pantalla-2026-08-26-143302.png&amp;type=ext\" alt=\"\" width=\"234\" height=\"242\"><\/p>\n","protected":false},"template":"","class_list":["post-462951","topic","type-topic","status-publish","hentry","topic-tag-error-3","topic-tag-mechanical-3","topic-tag-mesh-3","topic-tag-meshing-2"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello all, I&#039;m facing a problem with a simulation in LS-Dyna (workbench suite).
