When validating a model, there are numerous action items to verify. For example: Are the mass and inertia properties correct for each part? Are the joint and motion constraints properly defined? Are inputs and outputs converted to the correct units? Are the contact parameters appropriate? Is the mesh sizing adequate for…
Have you ever asked yourself these questions while modeling? “I have a component that is allowed to move 5 mm in both the positive and negative Z directions. How can I define that limitation?” “I have two large components that only come into contact at a single point, but the model takes a long time to export due to…
In the 2025.1 release of Inspire Motion, there is a known issue where the FlexContact+ feature is not working as it should. After running an analysis with FlexContact+ selected, the final result actually shows the non-enhanced flex body, not the enhanced. Image: FlexContact+ feature, located under the motion Run Settings…
