Hi all,
I have a general question regarding frequency domain simulations.
I've been doing frequency sweeps in frequency domain simulations a lot. Usually for a small change in frequency (for example a fractional change < 1% far from a resonance), the solution also only has a small change. Thus I'm wondering is it possible to use the solution from the previous frequency as the initial guess for the next frequency? This would be extremely helpful if it reduces the time needed for convergence for big 3D models.
I have attached a toy model as an example of frequency sweep in frequency domain simulations.
Thanks! Wentao
