Crucially, I need the model to be separated into two distinct solid bodies: &lt;strong data-path-to-node=&#8221;16,2&#8243; data-index-in-node=&#8221;167&#8243;&gt;cortical bone<\/strong> and &lt;strong data-path-to-node=&#8221;16,2&#8243; data-index-in-node=&#8221;185&#8243;&gt;cancellous (trabecular) bone<\/strong>, so I can assign different material properties to them (e.g., Young&#8217;s modulus).&lt;\/p&gt;&lt;p data-path-to-node=&#8221;16,3&#8243;&gt;Does anyone have a segmented model in a solid format (&lt;code data-path-to-node=&#8221;16,3&#8243; data-index-in-node=&#8221;54&#8243;&gt;.STEP<\/code>, &lt;code data-path-to-node=&#8221;16,3&#8243; data-index-in-node=&#8221;61&#8243;&gt;.IGES<\/code>, or SolidWorks\/Parasolid) they would be willing to share for academic\/research purposes?
