Er… so what's your boundary condition of θ, in traditional math notation? BTW I think it'll be better if you mention some background information of your PDE.

You've made a small mistake. y[L] == 0 and y''[L] == 0 can't be used in the first half as boundarys. If you Show the numeric and symbolic result, you'll see they're different :)

Interesting……Well, does this mean if we stick a infinite thin rod on an unbroken membrane, the membrane won't have any displacement except on the stuck point?
