in this substitution really is hard to substitute which i don't have idea how find u[1]  u[2] so on becuase  in that term some function like u[i,x] appear and i don't have idea how define them to remove it in my iteration ? and how remove the conjugate of function u[0] i did try evalc(u[0]) and make it worst than this 

which i did some special substitution which i don't know true or not but result is true i didn't have other idea for that
which  instead of any conjugate i use v and istead of any diff(u,x) i use z[i,x] and if conjugate have derivative v[i,x]
