Hi there,
I'm starting coding with OpenFOAM and I'm confused that there are some files holding same names and contents under
OpenFOAM-4.1/src
and
OpenFOAM-4.1/applications

For example, we have
/OpenFOAM-4.1/src/mesh/blockMesh/blockMesh/blockMesh.C
and
/OpenFOAM-4.1/applications/utilities/mesh/generation/blockMesh/blockMesh.C

My question is, why do we need the same file in different folders?

If you'd open those files, you'll see that they are not the same.

src:
All OpenFoam libraries' sources. This code doesn't do anything on its own: it needs an executable to require them in order to be executed.

applications:
All executables, like solvers and pre-/postprocessing utilities.
These executables typically use (a lot of) source code from OpenFoam's libraries by linking the libraries (see: Make/options that resides in every solver directory etc.).

In the case of blockMesh,

• the file in 'applications' only has a main method, it requires the file in 'src'.
• the file in 'src' does all the hard work

So both codes are together used when compiling.
Thanks a lot!
