Can I get double longitudinal coordinate?

Please login with a confirmed email address before reporting spam

In piezoelectric device analysis, I want to get a 1D plot result. The horizontal ordinate is frequency. I want two longitudinal ordinate in one plot, one is for voltage magnitude, and another is for voltage phase. How can I realize it? Thanks!

Hi

there are several (partial) ways but the one I use mostly is to define a Derived Value, and get out a table, you can add several columns to a table coming from different "Derived Values"

Thereafter you plot the table by clicking the plot icon on the table header, and you adjust your lot parameters.

However, I cannot remember to have managed to get a "dual scale" plot in COMSOL so you have an issue with the vertical scale it's either Hertz or 2*pi radians but not both (or has there been an upgrade there in V5.1 ? that I might have missed ;) for that type of plots you need to use the Excel or Matlab interface

Good luck
