Problem

I am having trouble with finding a solution which satisfies the boundary and initial conditions to this PDE:

ut=2u2x\frac{\partial u}{\partial t} = \frac{\partial ^2 u}{\partial^2x}
where u=u(x,t)u=u(x,t), 0xL0 \leq x \leq L
with boundary & initial conditions:

BC1: u(x=0,t>0)=Tfu(x=0,t>0)=T_f;
BC2: u(x=L,t>0)=Tiu(x=L,t>0)=T_i;
IC: u(x,t=0)=f(x)u(x,t=0)=f(x)
