Detailed Description

Geometry calculation scheme with explicit sync of face-geometry across processor patches.

applies face centre and normal (negated) to the neighbour side of a processor boundary.
recalculates the resulting cell volumes.
mainly interesting in single-precision in that it removes the different truncation error from circulating in different order. This can cause problems when calculating global transformations.
it does change the face normal/centre so might affect the cell-closedness of the attached cells.

Usage

In system/fvSchemes add a geometry scheme:

geometry
{
    type            parallel;

    // Optional underlying geometry scheme. (default is basic)
    geometry
    {
        type        solidBody;
    }
}

The default behaviour will print the total number of adjusted face and cell properties:

    parallelFvGeometryScheme::movePoints() :
        adjusted geometry of faces:113 of cells:54

In addition a warning will be printed if an internal face gives a different result.
