Detailed Description

2-D grid-based forward Euler diffusion solver.

This class implements 2-D grid-based forward Euler diffusion solver using second-order central differencing spatially. Since the method is relying on explicit time-integration (i.e. forward Euler), the diffusion coefficient is limited by the time interval and grid spacing such as: $\mu < \frac{h}{8\Delta t}$ where $\mu$ , , and $\Delta t$ are the diffusion coefficient, grid spacing, and time interval, respectively.
