1st Step to OpenFOAM

-

Documenting my learnings from the course OpenFOAM Programming Course by Flowthermolab.

 Sometimes you want to follow some tutorials online. They use various versions of OpenFOAM, some can even be outdated. And the underlying code is different, I find it tricky to adapt a different version to the one used in the tutorials/courses. 

  1. If a few versions exist, need to source from $HOME/.bashrc.
  2. Open terminal Ctrl + Alt + T
  3. gedit $HOME/.bashrc
  5. Add in the required aliases.
  6. In my case:
  8. Save and close the file.
  9. Open a new terminal.
  10. Check if alias works.
  11.  
  12. Also create user application and library folders to ensure user defined/modified solvers, libraries etc are separate from source code.
  13. Output from terminal showing if we don't have user defined folder run made beforehand, then using mkdir -p $FOAM_RUN, there now exists an empty run folder
  15. Let's try to copy a test case file to test our installation.
  16. Copy DynamicList from openfoam_directory/applications/test/DynamicList
  17. Attempt to compile wmake on test cases fails 

  19. Try changing directory read-write access
  20. https://askubuntu.com/questions/163589/cannot-create-file-directory-in-home-directory
  23. Dynamic List has now been compiled in user folder.
  24. Run with Test-DynamicList in terminal to get this output
  26. Full terminal output
  27. jk@JK:~/OpenFOAM/jk-v2312/test/DynamicList$ Test-DynamicList

Thoughts on open sourcing education

Over the past few months, with sufficient professional and personal motivation, I have learnt much and continue to learn more in the following areas, through the magic of Youtube: Microfluidics from Prof. Suman , courtesy of the NPTEL. I am grateful that such a detailed and fundamental treatment of an area of ongoing development has been shared with the public for free. The course starts off with the motivation behind microfluidics and how it is being applied in nature, and how it benefits us to apply it in engineering. I skipped to the videos on pressure- and surface tension-driven flows which cover extensive derivations on parallel plate flows, infinite and finite width channel flow to the dynamics of contact line influencing surface tension-driven flow profile near channel walls. I admit I do not understand everything and, as an engineer, I am mostly interested in applying the final set of analytical equations. However, the fundamental treatment from first principles definitely prov

After compiling, we would like to run the program.    Directory currently looks like this:     Attempting to run in terminal with an incomplete case directory results in this: This is because the system file controlDict is a pre-requisite, but it cannot be found. Copy and paste system files from a tutorial case into the Lesson1-HelloWorld directory The program is happy to run now.
