Hello everyone, first of all thank you for this wonderful software and also the forum platform for help.
I am trying to calculate force applied on femur by hip for my subject, but as I plot I get values ranging in 9000 to 14,000. Why is that so? What step I might be doing wrong?
I am attaching a picture below for clarification.

Hi Akshay,

Probably, you are not applying the muscle forces that should be calculated prior to using joint reaction analysis. The joint reaction analysis expects that you provide a file with the values of the muscle forces. You are getting very high reaction loads because the state of the muscle is not properly initialized and the calculations are wrong. Please, look at the following video to help you understand how to properly use the tool:

Solved, Thank you.
