error：Contact "Contact 0" under "Mode1"references a flexbody graphic that contains T cconnections. Graphics with T connections are not al1owed in contact simulations. [Genera1]
Hello Weidong,
Thank you for reaching out. The flexbody graphic is referenced in the body entity editor.
You can also double check the connection of the contact.
The error does indicate that the flexbody file that was generated has T connections. Please go through the original file that was created in a FE tool (Hypermesh) and double check the mesh quality.
If your model only consists of the two helical gears, you could recreate this model relatively quick in Inspire Motion, apply motion constraints (joints/motors/actuators/springs/etc) and generate the flexbodies there.
