Hi,

I am trying to model an inductor with a magnetic core in 1) Stationary analysis and 2) Frequency domain analysis. I have followed the instuctions in the sample model for a Spiral Inductor for the setup of the Stationary analysis. However, while solving the model, I get a singular matrix error that there are thousands of void equations. Did I not include certain required variables?

Thanks.
