You have to provide initial conditions for x1 and x2 and their first derivatives.

Success!

Success!

Your problem is too big for Prime, and lacks data:

- Prime 8 is crunching for almost 2 hours on the solution and hasn't found it yet.

- You need to supply the initial conditions for x1 through x14 and their derivatives.

Thank Luc

I think if we solve as symbolic may not need initial condition,
