#### Phase Difference

Hello,

On my HFSS model, I calculated the total current delivered to the object by using fields calculator:

Intergrate(Surface(Object)), Mag(Real()))

Let say the result is 50mA. I assume that if the voltage and current are in phase, 50mA is what I need. If they are out of phase, I need more than 50mA to power the system.

How do I find out if the voltage and current are in phase or out of phase in HFSS? (plot?, calculation of the angle?)

Thank you.

Did you try assigning output variables. Please go through this link - Ansys Electronics 2022 R1 - Post Processing and Generating Reports.
Then using this variables, you can either calculate or plot the phase of both voltage and current.
All the very best Praneeth.

what do you mean the voltage and current are in phase?

Is there other way to access the page? The link directed me to the login page and asked me to complete the registration. After I filled out everything and submitted, I got the following message. Then I clicked on the login page and had to fill out again. The message popped up again, and thus I couldn't access the page.
Thank you.

Hope this helps.

Do youuse a machine toolkit for simulation to get an efficiency map, i am facing an error when I simulate this tool in ansys electronic desktop version 2022 R1. Do you have any suggestions to resolve this problem?
thanks a lot.
