Equation (1) is known as a one-dimensional diffusion equation, also often referred to as a heat equation.With only a first-order derivative in time, only one initial condition is needed, while the second-order derivative in space leads to a demand for two boundary conditions.

Consider a metal bar of cross-sectional area, $A$, initially at a uniform temperature, $\theta_0$, which is heated instantaneously at the exact centre by ...

Jan 24, 2020 · fd1d_heat_implicit. fd1d_heat_implicit , a Python code which solves the time-dependent 1D heat equation, using the finite difference method in space, and an implicit version of the method of lines to handle integration in time. A second order finite difference is used to approximate the second derivative in space.

Here, I am going to show how we can solve 2D heat equation numerically and see how easy it is to “translate” the equations into Python code.

Here we treat another case, the one dimensional heat equation: (41) ¶. ∂tT(x, t) = αd2T dx2(x, t) + σ(x, t). where T is the temperature and σ is an optional heat source term. Besides discussing the stability of the algorithms used, we will also dig deeper into the accuracy of our solutions. Up to now we have discussed accuracy from the ...

I've recently been introduced to Python and Numpy, and am still a beginner in applying it for numerical methods. I've been performing simple 1D diffusion computations. I suppose my question is more about applying python to differential methods. I'm asking it here because maybe it takes some diff eq background to understand my problem.
