Simulation allows you to see when stiffness changes, load paths evolve, and stresses concentrate as parts come into and out of contact.<\/p>\n<p>To properly simulate the real world, you have to accurately define the system and how individual components interact with each other.<\/p>\n<h2>What Defines Contact Interactions in 3DEXPERIENCE SIMULIA?<\/h2>\n<p>Contact interaction is when components in an assembly or any mechanism touch each other. Contact is inherently nonlinear in nature, and capturing behaviors is important when simulating the performance of multibody parts or assemblies.<\/p>\n<p>Ignoring contact can lead to overly stiff parts, unrealistically low stress, or hidden failures. Depending upon the type of simulation tool used on 3DEXPERIENCE, you can define contact interactions in a variety of ways.<\/p>\n<ul>\n<li><strong>Tie Connection:<\/strong> Used for welded or bonded regions where relative motion is not allowed.<\/li>\n<li><strong>Frictionless Contact:<\/strong> Model smooth interfaces that allow sliding without resistance.<\/li>\n<li><strong>Frictional Contact:<\/strong> Enter user\u2011defined friction coefficients to simulate realistic load transfer and potential stick\u2011slip behavior.<\/li>\n<li><strong>Separation and\/or Overclosure: <\/strong>Surfaces can separate apart or close to form a tight or interference fit.<\/li>\n<\/ul>\n<h2>Interaction Property Definition<\/h2>\n<p>The Linear Structural Scenario creation app, available in SOLIDWORKS Simulation Designer and Structural Engineer roles, allows users to define interaction properties to clarify behavior between surfaces.<\/p>\n<div id=\"attachment_75289\" style=\"width: 610px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-75289\" class=\"wp-image-75289 size-medium lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.javelin-tech.com\/blog\/wp-content\/uploads\/2026\/03\/Contact-Prop01-600x433.png\" alt=\"Defining contact interactions in 3DEXPERIENCE Simulation\" width=\"600\" height=\"433\" title=\"\"><p id=\"caption-attachment-75289\" class=\"wp-caption-text\"><noscript><img decoding=\"async\" class=\"wp-image-75289 size-medium lazyload\" src=\"https:\/\/www.javelin-tech.com\/blog\/wp-content\/uploads\/2026\/03\/Contact-Prop01-600x433.png\" alt=\"Defining contact interactions in 3DEXPERIENCE Simulation\" width=\"600\" height=\"433\" title=\"\" srcset=\"https:\/\/www.javelin-tech.com\/blog\/wp-content\/uploads\/2026\/03\/Contact-Prop01-600x433.png 600w, https:\/\/www.javelin-tech.com\/blog\/wp-content\/uploads\/2026\/03\/Contact-Prop01-768x554.png 768w, https:\/\/www.javelin-tech.com\/blog\/wp-content\/uploads\/2026\/03\/Contact-Prop01.png 890w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/noscript> Defining contact interactions in 3DEXPERIENCE Simulation<\/p><\/div>\n<p>This capability is incredibly useful to engineers focused on safely bringing new designs to the table.<\/p>\n<p><strong>The Interaction Property dialog box behaviors include:<\/strong><\/p>\n<ul>\n<li>Penetration resistance, including hard, soft, or user-defined contact.
