Thank you very much for your answer. I have watched your tutorial videos to learn how to implement the problem but actually I have difficulties to input my own geometry in dealii and refine the certain line that I need to.Currently I play with the step-1 and step-12 again, which implements the refinement but as I said I have to change both the direction of the refinement and the geometry.Could I find somewhere in the tutorials how to do them? Thank you.
