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
