Scattered magnetic field in COMSOL 4

Hi! I am using the RF-Module ==> Scattered Field Formulation.
I want to calculate the scattered power only. In version 3.5. I could therefore use scEx scHy etc. Now there seem to exist variables called mod1.scEx etc. but no variables called mod1.scHx etc.
How can I access the scattered magnetic field?
Furthermore, is there a complete list with all internal COMSOL variables and constants? I know that I can turn on the equation view, but this is a very complicated way to search for names of constants and variables.

Hi

probably it's calles mod1.emw.scEx or just emw.scEx, check the "equations" sub-node

Good luck

I am also looking for a complete list of comsol internal constants.

If there is no complete list, you mention that you can view them by turning on equation view. I have equation view turned on but where are you looking?

(version 4.0a, windows xp)

Hi

the internal Comsol equations appear in the last subnodes (lowest level), the names adapt and changes depending on the physics, and the type of solutions.

You can also get lists in the postprocessing Plots, by hitting CNTRL + space in the variable fields
or using the <> gree/red arrow button
