I noticed the recent addition of TLM by User:Petkr which makes me wonder if we should perhaps add something to this article on some of the tradeoffs between different coupling methods. For example TLM's usefulness is limited to timesteps on the order of the propagation time in the transmission line. This is quite short in for example a driveshaft (100s of µs), compared to the simulation of an entire vehicle (10s of ms). Similarly Jacobi is only stable for timesteps on the order of the fastest mode in the system, which is problematic for stiff systems. KetchupSalt ( talk) 19:28, 6 March 2022 (UTC)
