Files exported from PETREL into EV and imported into LaGriT for Meshing and Model Setup.
Small_Model_Surfaces.zipx - these are the surfaces from the small model at 300x300 res
olution in EarthVision format. The user needs to know that I selected the option to reverse the sign of Z on export to make it conformal with normal earthvision convention.
File names changed to *.dat so EV could find and read the files and renamed for order from 000 bottom to 007 top.
Grid_space: 1431000.000000,1479100.000000,640000.000000,710100.000000
There are 1348724 (962x1402) lines in the file defining the surface of 1346361 (961x1401) cells.
Therefore start cell center is x,y at 1431025, 640025 and these surfaces define vertices with start x,y at 1431000, 640000.
These surfaces have 962x1402 = 1348724 node vertices
With x,y extents of 48100x70100 feet, Cell spacing is 50
The BigSky Eclipse Model uses Z values as depth.
LANL convention with LaGriT and FEHM uses Z values upward (above mean sea level).
