Dear, Im a PhD student dealing with geostatistical facies mapping,
Im using KT3D from GSLIB (Deutsch and Journel, 1992) to make some facies maps. Im working with rather large grids, and Ive realized that the following parameters located in the kt3d.inc file: MAXSBX (maximum super block nodes in X direction), MAXSBY (maximum super block nodes in Y direction), and MAXSBZ (maximum super block nodes in Z direction), had a huge impact on the computer time spent for interpolation. These parameters are used to subdivide the model in super blocks in order to speed up the searching data process. If these parameters are set small, setting the superblock scheme is fast but interpolation is slow, whereas if they are set large, setting the superblock scheme is very slow whereas interpolation is faster. I suspect that the results will be the same if independently of these parameters. But Im not sure if using too small numbers could lead to inaccuracies on kriging results. I would appreciate if anyone can provide some guidance on the correct numbers to use. Thank you.
