The most consuming task of the CFD simulation process is generating a mesh.
And there’s good reason too…
A poor mesh can:
-
introduce artificial diffusion
-
ruin any turbulence modeling
-
destroy numerical convergence
-
de-sta...
Computers do love physics...
I began my journey into programming physics engines and solvers about 7 years ago now, whilst an active Senior Mechanical Engineer in London, UK.
It was excruciatingly painful but equally rewarding in a variety of ways…

OpenFOAM / CFD is NOT that hard...
It was released over 20 years ago and has become popular ever since.
If you think about it, it generally follows the CFD / computational process that pretty much exists in most simulation workflows to this day…
CAD → Mesh → Solve → Result...
Tinkering some more with snappyHexMesh

So much so, they leave it for another, often commercial alternative.
Always start with a refined mesh near the walls, SHM did a good job with the distance refinement...
Meshing Setup vs Strategy
Before I get into this one, I wanted to remind you that The OpenFOAM Diet is now available to read! You’ll actually start learning how to use OpenFOAM properly without the fluff and confusion. (You’ll also be supporting my continued effort...
