Normalized error versus cell count in the mesh convergence study

OpenFOAM 14 Case 02: Mesh Convergence Study on a Laminar Channel

Written by giux | Published on Sep 22, 2026 | No comments

The same laminar channel on three meshes (2,000, 8,000, 32,000 cells): the error against Poiseuille scales with order about 2. How to set up and read a mesh convergence study in OpenFOAM.

OpenFOAM 14 Case 01: Laminar Flow Between Parallel Plates, Validated Against Poiseuille

Written by giux | Published on Sep 21, 2026 | No comments

First case of the OpenFOAM 14 path: a laminar parallel-plate channel built from scratch with blockMesh, solved with foamRun and validated against the Poiseuille profile (0.15% error).
