Hello everyone! I am currently playing with an old(adsbygoogle = window.adsbygoogle || []).push({}); analog computer, which could solvetime-dependentODE/PDEs pretty fast, without time-stepping. But the problem with analog computer's solutions is that they are not very accurate. I am very curious that is there any numerical method/solver which can take an approximate solution (over the time domain) to further process it, and generate a more accurate solution??

Thanks in advance!!
