Position

This field function displays the position of the vertices relative to the origin. It is available at vertices, faces, and cells. At faces and cells, the value represents the position of the respective face and cell centroids. This field function is the preferred option for specifying position dependencies of profiles and material properties when using field function methods. Position can be displayed as a Magnitude or as Laboratory coordinates. For a cell, the position is returned as the average of the positions of the vertices of the cell. This field function is the preferred option for specifying position dependencies of profiles and material properties when using field function methods. For more information, see Space Field Functions Reference.
