Explicit vs. Implicit time integration and the CFL condition

10 key concepts everyone must understand in CFD / By

When setting up a simulation and running it as an unsteady simulation or even just a steady state simulation with pseudo time stepping, we need to decide if we want to use explicit or implicit time stepping. The choice will have consequences down the line, and we need to be aware of them. In this …

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 …
