In this lecture, we will demonstrate how to create a mesh for the backward-facing step geometry using blockMesh in OpenFOAM. We'll explain how to define the block structure, and introduce concepts such as simple grading and edge grading, detailing what these parameters mean and how they influence mesh resolution. You will learn how to modify grading to control element size distribution, especially near walls where higher resolution is required. Finally, we will compare the blockMesh output with a triangulated mesh to highlight how blockMesh offers fewer elements and better control over mesh density—making it an efficient choice for structured meshing. 00:00 – Introduction to blockMesh and structured meshing 01:00 – Understanding block numbering and vertex indexing 04:00 – Creating backward-facing step geometry in OpenFOAM 06:00 – Writing the blockMeshDict and adding vertices 08:00 – Setting divisions and mesh resolution for each block 11:00 – Applying simple and edge grading to control mesh density 16:00 – Adding boundary labels, verifying mesh, and final comparison 🔖Keywords: OpenFOAM blockMesh tutorial, backward facing step OpenFOAM, blockMeshDict example, OpenFOAM structured mesh, blockMesh grading, simple grading OpenFOAM, edge grading OpenFOAM, OpenFOAM meshing tutorial, OpenFOAM blockMesh explained, CFD meshing OpenFOAM, backward facing step CFD, OpenFOAM geometry setup, OpenFOAM mesh generation, OpenFOAM beginner tutorial, OpenFOAM step by step, blockMesh OpenFOAM explained, OpenFOAM mesh refinement, CFD mesh grading, OpenFOAM mesh quality, OpenFOAM blockMeshDict file
