The following example is the one which demonstrates the ability to overwrite some PIL fragments by the PLANT sequences.
The case is concerned with the calculation of z-direction step size for parabolic problems. The case 150 is loaded from the core library and appended by PLANT blocks. They create the GROUND codings for composite function governing the distribution of grid steps in Z-direction: DZ is proportional to the Y-extent of the grid for the first two steps and each next step size is reduced as longitudinal centre-line temperature decay dictates.
