Hi everyone, I'm doing some simulations on a dataset containing young and old adults gait data. I want to compute the metabolic rate based on Umberger2003/2010 model by adding metabolic probe. but I think (based on literate) that the muscles' slow/fast twitch ratios are not same for young and old su...

Hello every one
How can we get the final value of the cost function in the CMC algorithm?

Hello Dear Forum Friends, Is there anyway that I can build muscles with sharing tendon? for example in the case of triceps surae muscles and Achilles tendon. I was thinking to add another muscle and set its maximum isometric force to zero and in this way I could consider it as a tendon. does this wa...

Hi everyone, I used the CMC tool to get the excitations of muscles, residuals and reserve actuators of my model during a gait cycle. I saw in one of the posts here in the forum that someone had used the CorrectionController to run the FD without strange behaviors so I implement the CorrectionControl...

Hi everyone I discovered the cause of this problem. as you can see below the ground reaction forces and markers' coordinates are not synchronized, and this problem leads the RRA toward the unusual response of the skeletal model. http://s6.picofile.com/file/8388983542/Annotation_2020_02_22_192654.png

thank you, Ayman, last night I changed the optimizer from "ipopt" to "cfsqp" and fortunately RRA algorithm run completely, but I figured out a new problem. the skeletal model had strange behaviors! I checked the ground reaction forces and it's "XML" file and compares it with other's templates. I thi...

Hi everyone I want to run Computed Muscle Control to compute a set of muscle excitations in the Rajagopal2015 full-body model. I use a data-set that has only 22 markers on the lower-body segments. I do Scale and inverse kinematic and RMS and max values are in the allowable regions. But when I try RR...
