The transformation ##u \to u-\fracVLx## will not influence your differential equation, but give u(L)=0. Solve the equation for the changed u, and add that linear section afterwards?

Interesting. Let's expand that a bit:

u=u(x,t)du/dt = A*(d^2u/dx^2)u(x,0) = f(x)u(0,t) = 0u(L,t) = V

Let w(x,t) = u(x,t) - (V/L)*x

Now,w(x,0) = u(x,t) - (V/L)*x = f(x)-[(V/L)*x]We can just name this g(x) so that's effective

w(0,t) = u(0,t) - (V/L)*0 = 0-0 = 0w(L,t) = u(L,t) - (V/L)*L = V-V = 0

dw/dt = du/dt - 0 = du/dtdw/dx = du/dx - (V/L)d^2w/dt^2 = d^2u/dt^2 - 0 = d^2u/dt^2

du/dt = A*(d^2u/dx^2) is given in the issue, and from above, because of this

dw/dt = A*(d^2w/dx^2)

So I resolve dw/dt = A*(d^2w/dx^2) the same means they do for the heat equation on wikipedia, then use the relation

u(x,t) = w(x/t) + (V/L)*x

To in finding u(x,t)

I feel that can work! Thanks!
