Here, I’ll cover the basic workflow that I implement when I am using cfMesh. First, when do I use cfMesh? I love cfMesh. I find it robust, easy to use … Continue Reading A cfMesh workflow to speed up and improve your meshing

When working on practical engineering applications, you often encounter problems where there are significant changes in temperature locally in the flow field. For instance, if you are doing a heat … Continue Reading Sutherland’s Law

kω-SST (komegaSST) Boundary Conditions Here the basic boundary conditions if you are using the kOmegaSST model in OpenFOAM: At the wall: ω (omega) – specific dissipation rate BC type: fixedValue BC … Continue Reading BASIC kOmega-SST Boundary Conditions

Here’s a useful little tool to estimate your wall spacing requirements to achieve a specific y+. It is based on flat plate boundary layer friction estimations. Therefore, it should only … Continue Reading y+ Calculator

This post is a simple demonstration of the timeVaryingFixedUniformValue boundary condition. This boundary condition allows a Dirichlet-type boundary condition to be varied in time. To demonstrate, we will modify the … Continue Reading Time-Varying Cylinder Motion in Cross-flow: timeVaryingFixedUniformValue

Establishing grid convergence is a necessity in any numerical study. It is essential to verify that the equations are being solved correctly and that the solution is insensitive to the grid … Continue Reading Establishing Grid Convergence

The Ahmed body is a geometric shape first proposed by Ahmed and Ramm in 1984. The shape provides a model to study geometric effects on the wakes of ground vehicles … Continue Reading The Ahmed Body

In this post I will go over the set up and solution of a pressure driven nozzle flow with a shock located in the diverging section. This refers to the … Continue Reading Pressure Driven Nozzle Flow with Shock – rhoCentralFoam
