Sabertooth Jaw analysis

Hi all
i have created a jaw model of Sabertooth jaw. I am using my motion
capture data to drive the front incisor point. i have given all the
attachment points based on the physical model. I am able to run the
inverse dynamic analysis but unable to figure out why the Temporalis
muscles are not producing any force or muscle activity. It would be
great if someone can help me with this. Please find attached a folder
“Sabertooth_Jaw_Final.rar” in files section. The main file is
“Jawmodel2.any”

thanks

Hey Srikanth,

I had a short look on your model. The Temporalis muscles produce some
passive forces, but it seems that for this load case (only gravity) the
Digastrics do most of the work and there is no need in activation of the
Temporalis. However if you add some loading to the model things are
changing. Then they will get activated.

Best regards,

Sebastian
