The following are all the parameters I am using for the simulation, either the net disappears or stays in the same place upon running, I have been trying to fix it for a couple of weeks now, I dont know what the issue is. If anyone can help me to see what inputs i might be missing or identify the problem and direct me into a right direction, that would really help me. I am using Altair Hypermesh 2025 for the pre-processing.&nbsp;&lt;\/p&gt;&lt;p&gt;Net: 10cm x 10cm in size, thread diameter = 1.1mm, made with 2D tria shell elements. The net needs to move towards the debris and wrap around it. Material model: MAT_58_LAMINATED_COMPOSITE_FABRIC. Section shell card: ELFORM = 16 (Fully Integrated Shell Element)&lt;\/p&gt;&lt;p&gt;Debris: 4cm diameter sphere, made with 3D tetra elements as it is a rigid body and is fixed. Material model: MAT_20_RIGID. Section solid card: ELFORM = 1 (constant stress solid)&lt;\/p&gt;&lt;p&gt;Velocity: Initial velocity generation at 4.5m\/s&lt;\/p&gt;&lt;p&gt;Contact parameters: CONTACT_AUTOMATIC_SURFACE_TO_SURFACE&lt;\/p&gt;&lt;p&gt;Then i have CONTROL_TERMINATION, CONTROL_TIMESTEP, CONTROL_ENERGY, DATABASE_BINARY_D3PLOT cards too.&nbsp;&lt;\/p&gt;&lt;p&gt;If you can help me, I can email you my key file. Thank you&lt;\/p&gt;&lt;p&gt;This is how both the mock debris and the net look in the software.&nbsp;&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/05\/11-05-2026-1778529006-Screenshot 2026-05-11 115636.png\" alt=\"\" width=\"274\" height=\"278\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-457973","topic","type-topic","status-publish","hentry","topic-tag-contact-method","topic-tag-lsdyna","topic-tag-simulation","topic-tag-solution-issue"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27814"],"_bbp_topic_id":["457973"],"_bbp_subscription":["652232","58821"],"_bbp_author_ip":["155.31.239.131"],"_bbp_last_reply_id":["457989"],"_bbp_last_active_id":["457989"],"_bbp_last_active_time":["2026-05-12 05:56:21"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["652232","58821"],"_btv_view_count":["48"],"_bbp_topic_status":["unanswered"]},"test":"mintuboyapatigmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/457973","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\/457973\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=457973"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
