I got an error when I want to find the numerical solution for this PDE. It says "Boundary condition is not specified on a single edge of the boundary of the computational domain." the code is following:
eqn = D[u[x, t], t] == D[D[u[x, t], x], x]
ic = {u[x, 0] == 1, u[0, t] == 0, Derivative[1, 0][u][10, t] == 0}
dsol2 = NDSolveValue[{eqn, ic}, u[x, t], {x, 0, 100}, {t, 0, 100}]
could anyone please give me some hint to solve it?
