Class
|
|
Foam::wallPointYPlus
|
|
|
|
Description
|
|
Holds information (coordinate and yStar) regarding nearest wall point.
|
|
|
|
Used in VanDriest wall damping where the interest is in y+ but only
|
|
needs to be calculated up to e.g. y+ < 200. In all other cells/faces
|
|
the damping function becomes 1, since y gets initialized to GREAT and
|
|
yStar to 1.
|
|
|
|
Note: should feed the additional argument (yPlusCutoff) through as a
|
|
template argument into FaceCellWave
