Hi guys, I'm new in geostatisics and trying to build a irregular grid in SGeMS to calculate variogram model. But I don't know how. Seems SGeMS can only set the number of cells in X,Y,Z direction and the size of each. I've seen a video in youtube did it but I don't know how. Here is a attached picture I grabbed from the video in youtube. Anyone know how to build the grid like that?
