Each solver has at least one tutorial which shows its use. Hello, I would like to give here a small guide (neither perfect nor exhaustive) for OpenFOAM beginners about how to prepare an OpenFOAM case. Maybe at this point you ask yourself the question: "Why should I invest my time into learning OpenFOAM?". This guide details the process of setup, simulation and post-processing for some OpenFOAM test cases, with the principal aim of introducing a user to the basic procedures of running OpenFOAM. This repository contains several OpenFOAM tutorials, cases and notes. The 6 most popular OpenFOAM community cases of the last 31 days, If no graph is displayed here, no javascript is working on your browser. This is my favourite tutorial, partly because it reflects what I do most of the time - low-speed, external aerodynamics - and partly because it's a great example of how the "mesh-solve-post-pro" stages fit together in OpenFOAM. If you are interested in contributing to the tutorial collection, here you can find the details on submitting new material. The license, under which contributors publish their material is stated on each page individually. If you want to give some feedback regarding the work done by Tobias, you are free to tell the community your thought about his work and share his site. Like most of the solvers present in OpenFOAM also this solver follows a segregated solution strategy. 1.4 Study of the discretization of the convective schemes. OpenFOAM Tutorial snappyHexMesh. Doxygen Guides-a4 lib: compiled libraries. where incompressible indicates the type of flow. Usually there is a steep learning curve, when one starts to learn OpenFOAM. Attention: We added a few errors in case C7 (missing or wrong keywords). The following topics will be covered: basic case setup initial values boundary conditions mesh simulation (2D elbow case with three meshes) post processing Second simulation - Lid driven cavity The geometry is shown in Figure 2.1 in which all the boundaries of the square are walls.
