For this, I need a system representation of the control system (P-PI-PI cascaded loop), a simple motor representation, the mechanical motion (a turning motor, spindle and a moving table) and ideally some mild FEM to simulate deformation in the spindle. I&#8217;m specifically interested in non-linear dynamics introduced by both the control system and friction within the system, so any coupling methods that imply linearity are out. Goals of the simulation would include a modal analysis of the whole coupled system (including the control) to gauge the impact of different design parameters (stiffnesses in the axis, control parameters,&#8230;) and some vibration analysis in motion. Ideally, the simulation could be run from the command line on an HPC. I do not want to investigate thermal influences or electrodynamic losses. I&#8217;m quite new to Ansys and am now wondering what the best practice for setting up such a system would be and feeling a bit lost in between Twin Builder, System Coupling and Workbench. If anyone could share some tips or experience, I would greatly appreciate it!&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-455190","topic","type-topic","status-publish","hentry","topic-tag-Twinbuilder-1","topic-tag-ansysmotion","topic-tag-digital-twin","topic-tag-mechanical"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27794"],"_bbp_topic_id":["455190"],"_bbp_subscription":["661953","88"],"_bbp_author_ip":["2a00:1398:4:2e09:8dc3:b4e6:e915:c829"],"_bbp_last_reply_id":["455398"],"_bbp_last_active_id":["455398"],"_bbp_last_active_time":["2026-03-30 07:06:16"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["661953","88"],"_btv_view_count":["101"],"_bbp_topic_status":["unanswered"]},"test":"marvin-frischkit-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/455190","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\/455190\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=455190"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
