Hi! I recently tried to perform a simulation of a physical process on Comsol Multiphysics (namely I tried ot find the harmonics of a musical instrument) and I felt incredibly lost at it. I'm normally good with computer programs, and I knew the overall physics of it, but I didn't even know where to start, and I couldn't find any good information on google. Could you point me to some places where I can learn how to use this kind of programs? Thank you for your time.
