Hello Ruoli,
I know it is probably too late to ask but I am curious whether you were able to solve this?
Did CMC follow the predefined x nodes for the concerned muscles?

Thank you Ayman for the clarification. Regarding what you mentioned that it may be a case of improper scaling, these files are from Rajagopal et al. "Full body musculoskeletal model for muscle driven simulation of human gait" OpenSIM version 3.3, the original unscaled Rajagopal and scaled Rajagopal ...

Hello,
After Scaling, the muscle attachment points are moved away from the bones. Is this expected behavior? If not, kindly tell me how to correct it.

Thanks for replying Mike. I am working on the Full Body Model developed by Rajagopal et al, where most of the lower limb muscles are represented as single line elements. I would like to split these existing single line muscles into two or more mucles. So yes my query is related to separating a singl...

Hi, I need some suggestions/advice as to how I can segment a single line muscle element into multiple line elements. For example if I had to model vastus intermedius into multiple lines, how would I set the optimal length and tendon slack length. I have gone through research papers but still have no...

Hi, Most of the muscles in OpenSIM models are modeled are single line elements. I wish to split a single line muscle like Rectus Femoris into two. The goal was to provide better representation and stability to the knee joint. I tried splitting the muscle by dividing the muscle volume into half and c...

Hi Yokhesh, I just came across your post and would like to ask how you combined two segments into one muscle. I wish to represent the rectus femoris muscle using two line segments instead of one, which is the case in most of the lower limb models in OpenSIM. I have already tried what Aaron suggested...

Thank you James for your reply. I apologize for seeing your post this late. Yes I understood what you said and also implemented the same. I had another question. Why do the RRA moment residuals increase with mass adjustments? The force residuals are very low but average moment residuals are around 2...

Hi Ursula, I am simulating a healthy walking trial with my experimental data. I too am having issues with model sinking and sliding a bit during the RRA simulation. GRFs have been applied on both the legs. The RRA residuals are also within the OpenSIM standard range, but it is the alignment of GRF a...

Hello, I am trying to reduce residuals by running RRA for a walking trial. I used the "Preview Experimental Data" to check the alignment of motion data with GRF and it looks good (Fig attached below). But as soon as I run RRA, my model goes down and then up. This I understand can be because of 1) ei...
