Under the Hood
================

If you look inside your project directory, you will find a ``foam`` directory with three subdirectories ``blockMesh``, ``snappyHexMesh``, and ``icoFoam``. We chose to break the work up into three subdirectories for convenience, so that you can, for example, the mesh from :program:`snappyHexMesh` doesn't overwrite the output of :program:`blockMesh`. We pasted a tree view below with all of the files generated by :program:`modelbuilder`. Although some of the files are simple and some are the same from one subdirectory to the next, more than a dozen nontrivial :program:`OpenFOAM` input files are generated and organized by :program:`modelbuilder` that would otherwise have to be authored by the user.
