I am solving a simple 1-D time-dependent PDE as follow ($a$ and $b$ are pre-defined coefficients):
$$\frac{\partial u}{\partial t} = a \frac{\partial u}{\partial x} + b T,\ t \in [0, T],\ x \in [0, L].$$
The initial and boundary conditions are given by:
$$u(t=0) = f(x), u(x=0) = g(t).$$
In simplest form,$f(x)$ and $g(t)$ can be constants.
Following is my code snippet. However, I couldn't find a easy way to implement the boundary conditions ONLY on one side of axis$x$ , namely $x=0$ . Consequently, results went diverged.
Do you have any suggestions to fix the problem?
