2.1.7.4. 1-D Look-Up Table

A 1-D Look-Up Table can be used to create a distribution of a scalars or vectors in one direction. Such a distribution can be used in:

A 1-D Look-Up Table is defined by an origin, a direction vector, and a column of at least one quantity varying along the direction vector. Location points can be defined in an arbitrary order. They are automatically sorted and duplicate location points are permitted for the definition of step functions. The values of the defined quantity are linearly interpolated to the element centers in the mesh. The 1-D Look-Up Table uses a scalar product to project the vector between origin and element center on to the Look-Up Table direction vector and look-up the desired value at that point.
