Class
Foam::AveragingMethods::Basic
Description
Basic lagrangian averaging procedure.
This is a cell-volume based average. Point values are summed over the
computational cells and the result is divided by the cell volume.
Interpolation is done assuming a constant value over each cells. Cell
gradients are calculated by the default fvc::grad scheme, and are also
assumed constant when interpolated.
