hello dear frineds
i work on static optimization of squat motion in GUI with rajagopal model.
my question is about the actuator file. i set the optimal forces in the actuator file and i got pretty good results.( otherwise the reserve forces are smaller than id output forces) but some activations are greater than 1. for exampe i attached two figure of forces and activations for pelvis tilt. may be please tell me that are my results correct? (when i increase the optimal force, the reserves increse and they become asame the id output)
the constraint violation is good but performance is so high.below is a part of performance and constraint violation .
time = 8.1 Performance =113.193 Constraint violation = 7.1653e-013
time = 8.11 Performance =132.42 Constraint violation = 7.79462e-011
time = 8.12 Performance =147.355 Constraint violation = 1.39866e-010
time = 8.13 Performance =160.488 Constraint violation = 4.50328e-010
time = 8.14 Performance =183.16 Constraint violation = 3.81495e-010
time = 8.15 Performance =205.945 Constraint violation = 4.50307e-011
time = 8.16 Performance =206.53 Constraint violation = 8.1939e-010
time = 8.17 Performance =204.775 Constraint violation = 2.2602e-010
time = 8.18 Performance =218.773 Constraint violation = 2.01003e-011
time = 8.19 Performance =238.044 Constraint violation = 1.48726e-010
time = 8.2 Performance =266.057 Constraint violation = 4.78695e-010
time = 8.21 Performance =303.149 Constraint violation = 2.19207e-010
time = 8.22 Performance =346.466 Constraint violation = 2.15759e-010
time = 8.23 Performance =395.451 Constraint violation = 9.89275e-011

Re: actuator file of static optimization
Have you confirmed that this model is suitable for the range of motion you are investigating? See Rajagopal, A., Dembia, C.L., DeMers, M.S., Delp, D.D., Hicks, J.L., Delp, S.L. Full body musculoskeletal model for muscle-driven simulation of human gait. IEEE Transactions on Biomedical Engineering, Vol. 63 (9), 2016: http://nmbl.stanford.edu/wp-content/upl ... al2016.pdf (page 11, paragraph before Conclusion section).i work on static optimization of squat motion in GUI with rajagopal model.

tanks for your reply
yes i searched and this model is sutible for squat motion
