The course homepage is http://www.tfd.chalmers.se/~hani/kurser/OS_CFD . If you intend to make a link to something at the homepage, please add the year to the address, such as OS_CFD_2013. If you are not attending the course, but find the homepage useful, please write me a couple of words (to firstname.lastname@example.org) that help me argue that this way of working is acknowledged.
The course is open to master students at Chalmers, and PhD students enrolled anywhere.
Other interested should contact me at email@example.com for information regarding industrial alternatives (OpenSource CFD for Industry – Basic Usage, and OpenSource CFD for Industry – High-level development, through Chalmers Professional Education - CPE), or just to be put in a mail list that is used for information regarding courses and conferences related to OpenSource CFD.
Some notes for master students at Chalmers: You will take this course under course code TME050, which means that you will be graded U/3/4/5. It also means that you can not use that course code for any other course, or if you have already used that course code you can not take this course. Talk to the student administration to make sure that you can take the course and that you can count it in your programme. Please see the formal syllabus of TME050.
If you are interested in taking the course you should contact me at firstname.lastname@example.org so that I can maintain an e-mail list that will be used for further information until the course starts. Getting closer to the start of the course I will ask for a verification (registration) that you will take the course for sure.
· Time: You should make sure that you have time to take the course. It is very intense the first three weeks, with two full hands-on lecturing days per week, and assignments for the next week. You are expected to dedicate at least 25h per week to the course the first three weeks. After that you have a certain number of weeks to do a complete project, and then you should review the work by another student. You should spend at least 175h in total. Don’t underestimate the work required!
· Fluid Dynamics and CFD: You should have a background in Fluid Dynamics, and ideally some CFD experience and/or a course in CFD.
· Project: You should be able to identify a suitable project that fulfils the requirements of this course, and that you are able to complete in the available time. It is beneficial if it is related to a project you are anyway doing, or planning to do (PhD project/Master project etc.), since it will be more useful to you and you will put more effort into it. We will of course discuss the project before you start doing it.
· Linux: The course requires you to have a basic knowledge in Linux. In order to be able to follow the lectures, you should make sure that you understand and can use the basic Linux commands presented at the link below. You need to have that knowledge in order to follow already the first lecture.
· Software: It is HIGHLY recommended that you make sure that you can run Linux and OpenFOAM from your own laptop. See instructions at the link below. We should have access to a computer lab with OpenFOAM installed, during the lectures and presentations, and you can try to find a seat there whenever it is not booked (or work from your FoDat computer if you have access to that, or remotely on one of our servers). On the other hand, you will gain more knowledge and freedom if you learn to install Linux and OpenFOAM yourself. We will not go through the installation procedures during the course, so you must do it before arriving.
The course gives an introduction to the use of OpenSource software for CFD applications. It has a strong focus on how to efficiently use the Linux operating system and different softwares that are useful for CFD (to the largest extent OpenFOAM, see the short description below), rather than having a focus on teaching the basics of CFD or fluid dynamics. A major project work in OpenFOAM forms a large part of the course. The project may be defined according to the student's special interests. The result of the project should be a detailed tutorial for a specific application or library of OpenFOAM. The tutorials will be peer-reviewed by the students, and the tutorials thus form a part of the course. The tutorials will be made available, as a contribution to the OpenFOAM community. To pass the course the student must do the project and peer-review a tutorial from another project. There will also be some compulsory minor tasks.
The students will learn on the following subjects:
Other software that may be of interest, but are not covered: salome, freecad, blender, engrid, gmsh, cubit, visit, Dakota
OpenFOAM (Open Field Operation and Manipulation, www.openfoam.com) is developed and distributed by OpenCFD Ltd at ESI Group and distributed by the OpenFOAM Foundation. OpenFOAM is an object oriented C++ toolbox for solving various systems of partial differential equations using the finite volume method on arbitrary control volume shapes and configurations. It includes preprocessing (grid generator, converters, manipulators, case setup), postprocessing (using OpenSource Paraview), and many specialized CFD solvers are implemented. The features in OpenFOAM are comparable to what is available in the major commercial CFD codes. Some of the more specialized features that are included in OpenFOAM are: sliding grid, moving meshes, two-phase flow (Langrange, VOF, Euler-Euler) and fluid-structure interaction. The strength of OpenFOAM is however the object-oriented approach to generating specialized solvers, utilities and libraries, using a flexible set of C++ modules. OpenFOAM runs in parallel using automatic/manual domain decomposition, and the parallelism is integrated at a low level so that solvers can generally be developed without the need for any parallel-specific coding. Due to the distribution as an OpenSource code it is possible to gain control over the exact implementations of different features, which is essential in research work. It also makes development and tailoring of the code for the specific application possible. In addition to the source code, OpenFOAM gives access to an international community of OpenFOAM researchers through the discussion board at the OpenFOAM home page. Community contributions are available through the OpenFOAM-Extend project at SourceForge (also at www.foam-extend.org).

Disclaimer: This is a student project work, done as part of a course where OpenFOAM and some other OpenSource software are introduced to the students. Any reader should be aware that it might not be free of errors. Still, it might be useful for someone who would like learn some details similar to the ones presented in the report and in the accompanying files. The material has gone through a review process. The role of the reviewer is to go through the tutorial and make sure that it works, that it is possible to follow, and to some extent correct the writing. The reviewer has no responsibility for the contents.
Project suggestions may be listed here (or see the previous courses), but you are encouraged to work in your own PhD/Master project, with a twist to make it appropriate in the current course. For inspiration, also see if there are master thesis suggestions below, where a part can be done as the project in this course. People visiting this web page may send suggestions to me at email@example.com.
· Improve the functionality for projecting blockMesh patches to stl surfaces, based on the work by Kalle Nogenmyr. It is currently (2013-12-17) using an external multigrid solver, amgpp, which is very slow except for very small cases. Further, it gives an FPE, so the OpenFOAM FPE check must be disabled. An alternative would be to use the OpenFOAM GAMG solver instead. Files are located here: https://github.com/nogenmyr/blockMeshBodyFit, and descriptions are located here: http://www.cfd-online.com/Forums/openfoam-news-announcements-other/119767-body-fit-capable-blockmesh.html. I think that Kalle would be happy to supervise a bit. Requires a skilled student.
· Continue the work on coupled solvers, by Klas Jareteg 2012, having Klas as contact person. Requires a skilled student.
There is no requirement to buy any book. You have to find the information you need to solve your project and the tasks.
The C++ part of the course is based on “C++ Direkt”, by Jan Skansholm, Studentlitteratur, which is in Swedish. Any introductory C++ book should be fine. Anyone who is doing CFD is recommended to have “An Introduction to Computational Fluid Dynamics: The Finite Volume Method” by Versteeg and Malalasekera. Another useful book is “Computational Methods for Fluid Dynamics” by J.H. Ferziger and M. Peric. Some useful references:
1. C++ how to Program by Paul and Harvey Deitel, Current version is 9 but older versions will also work fine.
2. Object Oriented Programming in C++ by Robert Lafore , 4th Edition
3. C++ from the Beginning by Jan Skansholm (should be a very good book for a complete basic programming newbie.)
5. C++ tutorial
1. The CoCoons project (community-driven documentation of OpenFOAM)
3. Documents related to OpenFOAM, collected by Professor Hrvoje Jasak.
9. An open code for blade geometry generation: http://engineering.dartmouth.edu/epps/openprop/index.html
