Hi foamers,

I am new to OpenFoam. I am reading source codes of pisoFoam.C to learn how it works, which has #include "fvCFD.H".

FvCFD.H file is in OpenFOAM-8\src\finiteVolume\lnInclude folder, but I found that I could not open it to see. So what was wrong? Any suggestion to help understand what happend?

Thank you!

Not sure what is valuable input here.

However, one way to proceed is to:

1/ go to the OpenFoam source directory using e.g. the "src" bash command

2/ use find to find the file using e.g.

find . -name fvCFD.H

3/ open the file using your favorite editor using e.g.

more ./finiteVolume/lnInclude/fvCFD.H

Alternatively, you should be able to view the file on Github.

I use notepad++ editor to open fvCFD.H, but failed. But it can open other .H files and .C files, like icoFoam.C. Only .H files and .C files in some folders I cannot open.
I dont know the reason.

From which OS are you trying to open the files? Linux or Windows?

the lnInclude directories only contain links (ln) and windows does not deal very well with these links so you cannot open it.

If you use the "find" command suggested by Domenico you will see the original fvCFD.H file is located here:

If you are using windows to navigate through the OpenFOAM directory, you might also have issues with some files due to the fact windows is not case-sensitive, contrary to Linux.
