7. Light transmission in optical fiber. Creating a model in COMSOL Multiphysics, exporting and editing, executing simulations and analyzing results in MATLAB.

Study Objective:

The course aims to introduce the possibilities offered by current numerical simulation of physical phenomena, particularly in relation to biomedical engineering. For these purposes, the COMSOL Multiphysics software platform will be used to perform numerical simulations of individual physical phenomena and their combinations. Furthermore, students will try to create a real anatomical 3D model using segmentation. This model will be used for numerical simulation in COMSOL or will be printed on a 3D printer.
