Hi foamers,

I am new to OpenFoam. To find all possible options for a parameter, I need to check the related source codes. How can I find them?

For example, I would like use multiphaseEulerFoam to solve fluidized bed. In constant folders, there is a phaseProperties file, where I need to define phases. To define phase particles, I need to specify parameters, including type, diameterModel, constantCoeffs, alphaMax and residualAlpha.

particles
{
	type         purePhaseModel;
    diameterModel constant;
    constantCoeffs
    {
        d               275.0e-6; // mean particle diamter 
    }

    alphaMax        0.63;   // maximum allowable packing fraction 
    residualAlpha   1e-6;   
}

How I find source codes related to these parameters so that I can know all options for these parameters?

Thank you very much!

Common methods include the "banana trick" (https://openfoamwiki.net/index.php/O...de/Use_bananas) -- e.g. to see what options are available for a given model input -- and foamSearch (https://cfd.direct/openfoam/user-gui...se-management/) -- e.g. to parse through the tutorials, I'd think. Otherwise, grep/find are always your friends (e.g., grep -r inletOutlet).

Thank you very much! It seems I have lots of documentations and commands need to learn.

The command "foamInfo xxx" will solver most problems, which often leads to "OpenFOAM/src/xxx" directory you can learn a lot about.
