My problem is this: [Initialize some functions at every remake in PDEProblem](https://discourse.julialang.org/t/initialize-some-functions-at-every-remake-in-pdeproblem/102078)

I’ve thought a possible solution would be to redefine

```julia
Temperature(t,x)

```

by defining a function:

```julia
function pde_solution(Tvec)
    interp = LinearInterpolation(Tvec, [1.,2.,3.,4.,5.])
    global Temperature(t, x) = interp(x)
    solve(prob, TRBDF2())
end

```
