non linear system using MUPAD

Hello everybody,

I´m trying to solve a non linear dynamic system of 20 ordinary differential equation using Matlab's symbolic toolbox '' MUPAD ''.

After setting the Equations and variables, it can run Solve(equat,Var), but without success. it's just replaced equations and variables without working out any variable !!

Equations are mainly consisted of: (x1(t),Diff(x1(t),t),Diff(Diff(x1(t),t)),x2(t),Diff(x2(t),t),Diff(Diff(x2(t),t)), x3(t), x4(t), ...etc). (Variables are coupled). Duration : t=5sec.

Too much variables ? how to integrate an ODE solver ? What's wrong ? I would appreciate your help to handle this non linear system ?
