Introduction The next step that follows the 2D buoyancy-driven melting of gallium is of course analyzing a 3D case and adding more physics to the solver. The question that we want to answer now is, how can we simulate a moving heat source, such as the tip of a
▶ Click here to watch the simulation In the previous post we developed a one-dimensional phase-change solver and verified it against the analytical Stefan solution. That case was pure conduction: the melt front advanced with time and remained flat. This was a very simplified case to validate the newly
In this post we will discuss how I created a very simple phase-solver. I want to explore and share how we go from defining a problem, deriving some mathematical models and quickly rewrite an existing OpenFOAM solver to add the equations that we have defined. What problem can be
▶ Check interactive visualisation In CFD, and in mathematical models in general, certain principles or equations cannot be solved analytically. Today we will explore one that can. We will work through some laws that all engineers might have already encountered across their studies, adding the circulation variable to the classic flow
