Hi, I have been trying to get this non-linear gear dynamics system of ODE's to solve but for the life of me cannot seem to correct the errors.
The attached sheet has several attempts at the end to write the equations and initial conditions in different formats but all give "too few initial conditions" or a"floating point error". Like most programming errors its probably glaringly simple!
Any assistance would be appreciated.
Regards,

The error tracing feature is misleading and incorrect in this case.
Your amplitude vector A starts with a value zero!
Using this the function Tzz will throw a division by zero error and so does Δkf used in the solve block.
So I guess you have three options:
1) Omit the first entry in vector A and use i := 1 .. N3 instead of i := 0 .. N3
2) define vector A so that it does not start with value AA := 0 but rather AA := 1 or AA := 10-6 or whatever seems appropriate
3) Rewrite function Tzz so that it will return a meaningful result if A=0.
Being lazy by nature I used option #1
and got this result
