Hi I am new to Mathematica and I have doubts with my code, I probably have errors with the boundary conditions. If you could help me I would appreciate it very much this would be my code
NDSolve[{\[Alpha]*(D[T[x, y, t], {x, 2}] +2.5*D[T[x, y, t], {y, 2}]) == D[T[x, y, t], {t, 1}],
T[x, y, 0] == to, Derivative[1, 0, 0][T][0, y, t] == 0, Derivative[0, 1, 0][T][x, 0, t] == 0, -k*D[T[L, y, t], {x, 1}] ==h*(T[L, y, t] - tam), -2.5*k*D[T[x, L, t], {x, 1}] ==h*(T[x, L, t] - tam)}, T[x, y, t], {x, y, t}]
I have taken care to put the 2 ==
