Question: How can I solve a system of DAEs which is not linear in all leading derivatives or leading dependent functions?

I have a DAE,ODE system which is not linear in all leading derivatives or leading dependent functions. This system is really big if I use explicit=true it goes for ever.

I need to know in what way I can use (dsolve/numeric, implicit=true) to solve this system?

Due to big big big system explicit is impossible.

and due to not being linear it can not be done by implicit=true.

Could you please help me?

How can  I solve this by maple?

Thanks,
