Interaction matrix extraction

[Rohit-Rangaraj]

Hey, I wanted to reach out to see if there is an easy/elegant way to extract the linear system that is solved to obtain the voltages and currents, in other words the interaction/impedance matrix.

I want to mess with my own solvers and post processing but extract the assembled interaction matrix for a driven problem.

Please let me know if there is a way I can modify the code or point me in the direction where the linear solve is taking place and I can take a stab at it.

Hi @Rohit-Rangaraj,

Thank you for your interest in Palace. Could you clarify a little what you're wanting? Is this the frequency domain solves, do you mean an impedance between ports? I'm not sure which voltages/currents you are wanting. If you are looking for https://en.wikipedia.org/wiki/Impedance_parameters, Palace outputs the S parameters, from which it is possible to calculate the Z parameters using the relationship given on that page.
