Which Current/Voltage Value is used by Coil Excitation in Coil Domain Interface: RMS or Amplitude?

Hello,

maybe someone can help me to figure out one "little" fundamental problem of understanding.

I build a modell of a coil which I would like to excitate with 10 Ampere RMS current. Further more I set up a study in the frequency domain at middle frequency-range 20 to 70 kHz.

Now I am a litte confused about which value is to be inserted as a Parameter of Coil Excitation in the Coil Domain Interface (e. g. Single-Turn or Multi-Turn Coil Domain): 10 or 10*sqrt(2) Ampere.

In the Documentation of "Coil Domains Feature" the talk is of "the total current or total voltage", but not of RMS or Amplitude?

Regards,
Denis

I had this exact same question awhile ago. This is what support came back with:

"When specifying current or voltage excitations, unless otherwise specified
the values you enter are peak values."

thank you Dennis, good to know I am not alone. Today I had an idea to test this with simple comsol modell and compare it to an analytical solution. I report my results here when it's done.
