Diffraction Pattern

Please login with a confirmed email address before reporting spam

Hello,

This is probably a very simple question. In the diffraction patterns example in the model library, how can I extract the amplitudes (or the intensity)?

Many thanks
Hamid

Hi!

You do this in the post processing. With your results, you get some default plots in 2D or 3D depending on the geometry, lets say you are working in acoustics (as I am) you get the pressure (Pa) and the SPL (dB). You can add more plots by right clicking on the plot group add the type you want, and choose other variables to plot i.e. Intensity, Vibrational velocity in x,y,z., acceleration etc.

You can then export the data if you want, look in the Comsol help for that part.

Hope this helps
