How to write a CFD library: Basic library structure

How to compile, write, and use CFD libraries in C++ / By

In last week’s article, we developed the discretised equation for the 1D heat diffusion equation using the finite volume method. We looked at why we need an implicit time integration technique and why this requires a linear system of equations solver. In this week’s article, we’ll explore how to set up a basic project structure …

How to write a CFD library: Discretising the model equation

How to compile, write, and use CFD libraries in C++ / By

In this article, I want to quick-start our discussion on libraries and introduce a model problem that is simple enough for us to code, yet can be exploited to show how we can develop a library that is solving a real-world CFD problem; solving the linear system of equations . While we are limiting ourselves …
