Solution at Phase?

Please login with a confirmed email address before reporting spam

Hi all,
I am new in Comsol. I am just wondering if anybody knows what the "Solution at Phase" is used for, which is in Postprocessor>>General.

Thanks a lot for help!

For frequency-domain problems (such as wave problems in electromagnetism or acoustics for example) the solution consists of information about one or more oscillating quantities. These quantities have magnitdue and phase. Often, it is useful to plot these quantities at specific phase angles of the oscillation in question.

Hi

It is another way to access complex values, depending on your physics and your model you get complex variables with Real an Imaginary parts as results.

The Z=a+i*b = r*e^(i*Phy) are just two equivalent ways of expressing complex values.
if you want more take a search on "complex number Wolfram" or on "wiki" (I prefer Eric Weisstein's pages)

If you are a "beginner" you would probably not start with that chapter, so just use your solution at phase = 0 or the real values

But ist great for more complex issues, in structral damping, or for EM (electromagnetism)

Good luck
