Hello everyone,(adsbygoogle = window.adsbygoogle || []).push({});

I am making use of Mathematica to solve differential equations developed by Lagrange method,

I have met some problems in solving the equations,

I cannot obtain the correct result even though I have set "t" and "MaxSteps" both as "Infinity". I have run the program for 7 hours, but it cannot stop calculation under the condition that

"Event"->(RLEy[[1,1]]).

I don't know much about how to set the parameters of NDSolve functions

properly in order to get correct results?

The program I have run is as the attached, I appreciate any help from you.
