Question:How do I plot the analytical PDE solution in maple

Hi!

I am a new user to maple and I have tried to solve a partial differential equation.

The solution is shown in the figure above but I don't know how to make a 3d plot or contour plot of the solution. The code of solving pde is down below:

restart;
pde := diff(T(x, y), x $ 2) + diff(T(x, y), y $ 2) = 0;
bc := T(0, y) = T1, T(a, y) = T2, T(x, 0) = T2, k*D[2](T)(x, b) = h*(-T(x, b) + T3);
sol1 := simplify((pdsolve([pde, bc], T(x, y)) assuming (0 < a, 0 < b)));

and the constant value are:  a = 250, b = 4, k = 2.091, T1 = -5, T2 = 0, h = 100, T3 = 1000

the plot range is 0<x<250, 0<y<4.

Thank you for helping me!
