Is there any way to say to the program that Y (Area/Nbeam) cannot be smaller than 0?

Maybe you can set a bound to parameter C to be >=0. See below:

No, I did not change it manually.
Attached is the project.https://my.originlab.com/ftp/forum_and_kbase/Images/F19%20beam%20on%20Pd%20targets_Avgust_2025.opju

Thank you.

Could you share your project here? It's strange because, according to the definition of your fitting function, y should always be greater than zero. Have you manually changed the y-axis tick labels? Thank you.
