Class Documentation

class MulticellLOTWWallModelFvPatchScalarField : public wallModelFvPatchScalarField 

Class for the wall models based on a law of the wall, sampling data from multiple cells. Currently hardcoded to use the integrated Reichardt law.

Needs a root finder to be defined. Unlike the single-cell law-of-the-wall models, this model fits the integrated law to a wall-normal profile sampled from several cells for each boundary face.

Usage

    patchName
    {
        type                MulticellLOTWWallModel;
        value               uniform 0;
        interpolationType   value; (default cell)
        sampler             value; (default Tree)
        lengthScale         value; (default CubeRootVol)
        hIsIndex            value; (default false)
        excludeWallAdjacent value; (default false)

        RootFinder
        {
            type            RootFinderType;
            otherParams     value;
        }
    }
