Repost (Boundary Condition NDSolve)

Dear Group,

I have a simple problem with NDSolve boundary condition. Here is a
file if anybody want to have a look. I have explained everything
there.
<http://www.mediafire.com/?6bx4exs8m0rdbkb>
My problem is how to implement periodic boundary condition for MOL
discretization. If the boundary condition is u[t,0]==u[t,1]==0 then my
method works but for u[t,0]==u[t,1] it shows large artificial effect
on the MOL solution.
Though the test PDE is tough one but I cant figure uot how to get rid
of this problem.

I know this forum has got some PDE experts. This question is addressed
to them. I hope some of you can guide me on this.

Regards,

Pratip
