In a 3D comsol model, how to output the solution on a specific line (in reference or current configuration)? In .mph comsol models, it's like the
comp1.at3
command that is equivalent.

Hi @feynman feynman,
To output the solution along a specific line, you can utilize the 'mphinterp' LiveLink API. This API allows you to evaluate expressions across arbitrary points. For more information on how to implement this API, please refer to the following COMSOL documentation:
https://doc.comsol.com/5.6/doc/com.comsol.help.llmatlab/llmatlab_ug_ref.9.25.html
Reviewing the examples on this page will provide you with a better understanding.
I hpe this helps!

thank you very much! I don't know if you have experience with 'cutline' data through and then with mphinterp: cln = model.result.dataset.create('cln', 'CutLine3D');
It seems that by default the output data is not on the FE mesh, so the user has to specify the coordinates?
