Hi,

I am running current density analysis on PCB board using a DC current source. Can we do similar kind of analysis using a frequency dependent current source or voltage source in SIwave? If yes then kindly elaborate a little bit.

Regards

Hello Andrew,
Yes you can carry out a current density analysis using a frequency dependent source voltage source in SIwave. One way of doing it is to use the "push excitation" option during SIwave+Circuit co-simulation of your pcb. Please try it out.

Hi Mrinmoy,

 I am not simulating specific circuit in SIwave. I have copper plannes at specific layers of board. The setup looks like this

Thanks for Sharing the image your set-up. As I mentioned, AC/Frequency-dependent sources can be assigned in SIwave and current density can be viewed. Either you define your current-time data as an input to the frequency dependent source OR use the push-excitation workflow for doing the same wherein you will define your excitations in the Ansys Circuit designer and push excitations back to SIwave. 

Additionally, such analysis can also be done in HFSS Classic and HFSS 3D Layout where you can view current densities in the planes.

Ok Thanks. let me try these and get back to you later.
