For example, when I want to analyse what line does, lets say there is line


const face compactFace(identityMap(newFace.size()));


I can guess that I am defining constant face named 'compactFace' and initializing as value identityMap(newFace.size()), where newFace is value given in the code before, so we can guess it will be initialized as identityMap(known value).


But problem here is that identityMap isn't forementioned in this code, so it must have been from other file which header is mentioned at start of the file.


Is there easy way to find origin of such function easily and figure out what these things do? Or is it only way to search for every class file mentioned?

You could use the C++ Source Code Guide: https://api.openfoam.com/2312/ or https://cpp.openfoam.org/v11/ (Depends on which OpenFOAM fork you are using.).

or you could use grep(https://linux.fandom.com/wiki/Grep) on your local OpenFOAM source code ...

This also looks like someone's special code definition somewhere. I would normally use the Foam identity() function:

const face compactFace(identity(newFace.size()));

If you go to https://api.openfoam.com/2312/ and type "identity" into the search bar. Currently it returns https://api.openfoam.com/2312/namesp...e588eab475eabf which gives a description:

  Return an identity map of the given length with (map[i] == i),
works like std::iota() but returning a list of label values.
Optionally with an alternative start index, so that (map[i] == i+start)
