Hey, AnyBody support,
Please find the attached zipped file of my model. Based on the MaxForceNeck model, I created the surgery equipments (light and eye glasses) in the environment file. The imported equipments were attached to the head using two prismatic joints. I used neck motion text file to move the cervical spine part.
The model can run the kinematic analysis very well. However, it cannot run the inverse dynamic analysis at all, saying " muscle recruitment solver aborted after maximum number of line-search iterations".
I tried many other ways to modify this model, like to reduce the data points or size of the text file, reduce tEnd, change the directions of gravity, or turn on/off the reaction.type… Still failed!
Could you please help me with this problem, so that I can run the inverse analysis well?
THANKS!
Sincerely,
Cathy
