Properties🔗
directionalMeshWave
is a variant of
meshWave distance-to-patch
calculation method, with which the distance component in a specified direction
can be ignored, e.g. the distance-to-patch can be computed in the wall-normal
direction only.
For a given point within a given mesh, the existing meshWave
method gives
the orthogonal distance to a specified patch. In meshes with very steep terrain
(e.g. a hill of 90 [deg
]), this might be problematic for the fields that
require the distance to the patch associated with the terrain surface.
An example of directionalMeshWave
output in terms of the wall distance
can be seen as follows:
