BC for transport equation using NDSolve
First I can solve a transport equation with a source (Is it still called transport equation?) using DSolve. The form of the source serves only as an example. It can be anything.
sol1 = DSolve[

NDSolve: Normalizing at every step
Suppose I have an transport equation with an initial conditions:
sol = NDSolve[{D[y[x, t], t] - 4 D[y[x, t], x] == 0,
y[x, 0] == 1/Sqrt[2 \[Pi]] Exp[-(x)^2/2],
y[10, t] …

Modify NDSolve`StateData (if possible)
I am trying to solve a PDE that needs to be scaled constantly (refer to this). @andre suggests I modify NDSolve`StateData.
Now, the problem is, I'm not used to the object-oriented side of Mathematic …
