I'm quite new to the smoothed particle hydrodynamics method, so I'm trying to find Matlab or Python code to help me understand it. Specifically, I want to know how to solve the one-dimensional diffusion equation like in this paper,
$$\frac{\partial u}{\partial t} = \lambda \frac{\partial^2 u}{\partial x^2}$$
SPH is reviewed in many good introductory texts, eg. Monaghan and Price papers. I understand the math/theory, but I'm trying to find a detailed simple code to see how things work numerically. I know there are software packages like DualSPHysics, but I prefer something basic for solving the above differential equation. Can you please help?
