Dear Shabnam,

Sorry I missed your post 3 days ago, once the discussion has been marked Solved, I may miss a new post.

If adjust to touch gives you good results that match experimental data, that is a good reason to use that adjustment in the model. I am glad to see that the remote point has the correct degrees of freedom that match the experimental setup. That is also very important.  It looks like you have a final result you can trust.

Best regards, Peter
