Grid Project:   Yucca Flat Mesh for Piledriver

Purpose of Project

This work models the area at the PILEDRIVER event.
The working point x=583786.8, y=4120276.7, z=1089 m Zones for spherical cavity radius of 45m, and a second cavity radius of 90m
The chimney zone has radius 50m and height 277.4m upwards from the working point
with a second chimney 100m and height 277.4m

Mesh extents are 2000x2000m around event center with zmin at 750. and zmax at ground.
Vertical spacing is 10m
Horizontal spacing is octree with 10m for 500m, 20m, then 40m for rest of mesh.
