Dear Kyusik, Cell iterators have the function set_material_id <https://www.dealii.org/developer/doxygen/deal.II/classCellAccessor.html#abe9098e74cd5e1bec7c01abbbf056e13>, so you can change the material ID of any cell at any time. If by
change the boundary of 2 materials you mean physically move the triangulation to change the spatial position of the interface between two different materials, then this is also possible. Look at step-18 <https://www.dealii.org/developer/doxygen/deal.II/step_18.html#TopLevelmove_mesh> for further information. I hope that this helps.
