  1. If you use Inspire then you can optimize the topology of a part in "one click". 1. open CAD files in Inspire 2. organize model into design space and non-design space parts (use partitions) 3. mechanize the model (ground, rigid groups, joints, motors) 4. define design space 5. run a motion event. 6. click 'Optimize Part' and run the optimization. 7. when optimization run finishes you have a new topology shape for the part. Optionally you can export the .fem deck in step #5 if you prefer. Attached video shows one of the motion tutorials on this in Inspire 2019.3 OP_Motion.mp4
  2. ... model and video are attached. impulsiveForce_IM.mp4 2_simplified_SingleBC_Impulse_2019.3.stmod
  3. Using Inspire Motion you can use a Force Actuator and prescribe the Impulse function like shown in attached image.
  4. If you don't like using 'points' you can use Inspire to create your multibody model easily from CAD. Just use the 'Motion' ribbon. It is very simple to create a functioning model without points. Then you can export it to MotionView (by MDL) and it will have points, should you want them.
  5. Do you have access to Inspire Motion? Attached model can be opened and exported to MDL format for use in MotionView. Sincerely, asajd TransJoints_MarkerMotion_wContacts_DEMO.mp4 TransJoints_MarkerMotion_withContact.stmod
  6. Perhaps you could model it with 3D contact, see attached video for proof-of-concept. BallStud_3dContact.mp4
  7. If you build your model with Inspire Motion you can perform structural (FEA) analysis of the rigid body mechanism. You can get stress results like shown in attached video. IM_stress.mp4
  8. With Inspire 2019.1 you can use the Joint Coupler to create a rotational-translational relationship between joint movements. Please find the attached model and corresponding video. In this example a preloaded spring has been placed between the nut and bolt to represent the compressive load as the nut is tightened. Hopefully you get the idea here. Good luck.

  9. For simple spur gears it is often much simpler to just use a Coupler... it can run very efficiently because contact detection is not required. See attached ZIP file containing a model where coupler is used instead of contacts. Sincerely, Tony S. Spur_Gear_useCoupler.zip
  10. Inspecting the MDL file you provided there appears to be a mismatch between the part name and the internally represented name embedded in the CAD. Think of it as being a 'mapping problem'. This isn't your fault. The attached 'LG_parts.txt' file shows what I believe the part mapping ought to be. Try using the attached MDL and Parasolids file and see if that works out better for you.
