What do you mean by "pretty big"? What's the expected amplitude? The initial value problem (IVP) solver for ODE in NDSolve is very robust and should always be the last thing to adjust. (Anyway, I tried adjusting WorkingPrecision to 16, but the solution just looks the same: i.sstatic.net/ZwtUP.png) Are you sure the system itself is correct?

| Sep 1, 2022 at 12:21 | comment | added | pixis | @xzczd I'm running 11.3 and yes I can get the solution too, I don't trust the solution because of the values which are getting pretty big. It gets worse if you took g1=0.1, g2=1 for example | |

For g1=0.5;g2=1 I get a solution in about 5 seconds in v12.3. Which version are you in?
