From CAD geometry to a mesh in OpenFOAM 14: a 3D channel with blockMesh, an STL sphere with surfaceCheck and snappyHexMesh, local refinement, wall layers and y⁺ estimation, checkMesh diagnostics, ParaView inspection and a pre-solver acceptance plan, with the complete files and expected values.

From a single case to a documented, repeatable CFD campaign with OpenFOAM 14: four cases from the cylinder tutorial, Bash scripts that never overwrite, SHA-256 fingerprints, serial or MPI runs, surfaceFieldValue measurements, mass balance, CSV collection of results and plotting from Windows.

In this first lesson, you will learn how to write and run a GNU Octave script directly in GX-TXT. We will open Octave Script Workspace, import an `.m` file or type the code in the editor, assign a Script ID, and launch the script. Using the public Script Bridge APIs, we will convert five temperature readings to kelvin, calculate their mean, and inspect the results and execution log in the Session.

A repeatable protocol to decide whether an OpenFOAM 14 result is trustworthy: quantity of interest, a family of three meshes, iterative convergence and balances, comparison with the Poiseuille solution, observed order, Richardson extrapolation and GCI, time-step study and physical validation, with a script and a verification record.

Using ParaView 5.13 with OpenFOAM 14 to measure, not just to visualise: profiles with Plot Over Line, section averages and flow rates with Integrate Variables, pressure drop, comparison with the Poiseuille profile and an RMSE error, recirculation regions, CSV export and reproducible PVSM states, client/server from Windows.

An operating guide to checking an OpenFOAM 14 run from launch to result assessment: reading the log, residuals and continuity, function objects for residuals and probes, monitoring pressure drop and flow rate with surfaceFieldValue, mass balance, diagnosing typical patterns and a reproducible assessment from Windows.

An operating guide to using OpenFOAM 14 installed on a Linux server while working from a Windows PC: preparing cases in Notepad++, SFTP transfers with FileZilla, running over SSH from PowerShell with tmux, inspecting logs with klogg and visualizing results with ParaView connected to pvserver through an SSH tunnel.

The final unit of the course: the official v14 documentation, foamDictionary, foamSearch, foamInfo, foamToC and foamFind, systematic error diagnosis and a capstone case built from an empty directory.

From kinematic viscosity in physicalProperties to laminar, RAS and LES models in momentumTransport: what changes in a case when the physics changes, which fields become necessary and how to verify it with the OpenFOAM 14 tools.

What happens after discretisation in OpenFOAM 14: the A x = b system, the solvers dictionary of system/fvSolution, tolerance, relTol and maxIter, GAMG, smoothers and preconditioners, Final entries, relaxation and the SIMPLE and PIMPLE algorithms, with labs and worked answers.
