I was wondering if anyone knew if it is possible to create an independent git repo within an existing git repo. Essentially, what i have is a CFD code i wrote. It carries a folder structure such as: repo =>caseFiles =>sourceFiles =>postProcess ^case file folders ^multiple directories ^multiple directories Now the issue is, I dont want to add the caseFiles to the repo, because they change case to case, and since this is a program used by many people i wouldnt want to overwrite other peoples cases. So the question is, how do i elegantly track my changes in my case files without hindering others using the git repo? I tried branching and adding, but the merging screwed everything up. Is it possible for me to create a separate repo within the casefiles folder? I hope i was clear... this is overall a rather confusing situation because this is a huge shared library of cfd solvers.
