      Hello,

      I’m new to using QUCS and right now I’m trying to see if I can port a implementation of a Josephson junction. My goal is to reproduce the current response of a voltage step function and how it evolves over time. However, there is a problem when using the transient simulation, the initial DC analysis does not converge.

      I’ve tried switching to only running a DC simulation but it has the same problem for multiple different convergence tolerance and maximum iteration.

      Any idea of what might be the problem?
