COMSOL 4.2
- EasyTutorials - Comsol Seminar with many Tutorials

Here are many tutorials that get you going with COMSOL. You don't need any previous knowledge about this program and will get to know the basics in order to perform your own simple simulation and analyse the obtained data. The tutorials should be seen in their right order because they are based on each other.


  • 01 - Simple Dipole Step by Step - This is just an overview how a full simulation can look like, just to give you a feeling what it is all about, you dont have to understand each step since everything is shown just very briefly and without deep explanation. After you watch all of the next videos, will can create such simulations and much more, easily!
    Plotted graphs:
    normalized timeavaraged power flux: sqrt(emw.Poavx^2 + emw.Poavy^2 + emw.Poavz^2)
    and the normalized wave: sqrt(Ex^2 + Ey^2 + Ez^2)

  • 15 - Example: Refractionc and Total Internal Reflection - This tutorial is a practical example how the Electromagnetic Wave module (RF) can be used to simulate an electromagnetic wave in a dielectric. It is shown, how the light is refracted or reflected at the dielectric-air interface. Simulation is done for different incident angles. It is clearly seen, when total internal reflection sets in and when refraction happens. Plotted and exported graphs:
    normalized timeavaraged power flux: sqrt(emw.Poavx^2 + emw.Poavy^2 + emw.Poavz^2)
    and the z component of the electriomagnetic wave: Ez
