Hi, I have just installed uSimmics and I’m trying the HB simulator.
It seems to me that it performs much better than in qucs, in particular it converges much more easier. However, I suggest to use one trick: if you want to pump the non linear device in deep compression use to sweep the power of generator from low power level up to compression. The simulator probably uses, as initial condition at the i-step, the output of the previous power step (i-1), this facilitates the convergence.
Very nice work, thanks to all developers that were engaged in uSimmics tool!!
