Issue with Conrods on custom engine about engine-sim HOT 3 CLOSED

For anyone wondering why some of the config was left alone/appears in other files while the rest is heavily edited/detailed: I'm still working on modeling the engine. There's very little documentation on the 7M-GE, and it already took me 5+ hours to write what I have, so stuff like the intake/exhaust isn't my biggest concern. I'm more concerned about the accuracy.

It looks like the moment of inertia of the connecting rod is too low. You can fix this by multiplying the moment of inertia by 10, So it would look from
connecting_rod_parameters cr_params( mass: 1723.651 * units.g, moment_of_inertia: 0.00002, center_of_mass: 0.0, length: (302.02 - 0.5 * 91 - 33.0) * units.mm )
To
connecting_rod_parameters cr_params( mass: 1723.651 * units.g, moment_of_inertia: 0.0002, center_of_mass: 0.0, length: (302.02 - 0.5 * 91 - 33.0) * units.mm )

Also fix your rod journal angles and make it like
rod_journal rj0(angle: (0.0 / 6.0) * 360 * units.deg) rod_journal rj1(angle: (2.0 / 6.0) * 360 * units.deg) rod_journal rj2(angle: (4.0 / 6.0) * 360 * units.deg) rod_journal rj3(angle: (4.0 / 6.0) * 360 * units.deg) rod_journal rj4(angle: (2.0 / 6.0) * 360 * units.deg) rod_journal rj5(angle: (0.0 / 6.0) * 360 * units.deg)

Overall, here is the fixed version of the file

Thanks! The engine seems to be working again, now I can get back to work!
