Understanding OpenFOAM code
2 Attachment(s)
I am trying to understand roughly what each method/function in OpenFOAM does by searching for it in the link cpp.openfoam.org.
As I went through the laplacianFoam.C, I got stuck with the member functions of "options" class namely constrain() and correct(). Scouring the above source code, I found the class definition and function definitions, which call member function of another class called "option" (source.constrain()), which was empty. I've attached below the screenshots. I've been having a bit of trouble understanding OpenFOAM code this way. Are there other easy ways of knowing what the functions do?

In order to understand OpenFOAM, try to do the following:
~ Work in debug mode till your code works promptly. The debug mode locates the error appropriately during compilation which helps to understand the code better. WM_COMPILE_OPTION=Debug ~ Try using gdb or nemiver debuggers which helps to navigate the code line by line from the scratch. https://openfoamwiki.net/index.php/HowTo_debugging ~ Create doxygen documentation for your customized solver. It's a good reference manual with source trees to easily refer the actual code. Hope it helps. Thank you |
