Hi Bruno, OK, let's see the simple example in step-3. From a physical viewpoint, this is a steady-state heat equation without a heat source. Then we hope there is a particular line area inside, where the temperature is, for example, 1. In other place, the initial temperature is 0. Under this condition, we solve the equation and get the temperature distribution around this line area. Why am I concered about this? Because I have a benchmark problem which needs the similar inner boundary conditions.
