Using InterpolatingFunction from NDSolve

I solved a PDE with NDSolve in Mathematica 5.1. I could plot, differentiate and integrate the obtained InterpolatingFunction object, the result being a similar object. I was able to integrate the 2nd derivative of it. What I need is to integrate the square of the obtained InterpolatingFunction object (the square itself does not simplify to such an object). You can see the details on my homepage: http://www.math.bme.hu/~tladics/nds.nb Every suggestions are welcome! Thank you, Tamás
