Hi Sean, You are right, the "other program" outputs one result for each cell. Option #1 would work but I want to pursue your option #2 a little further.
Can you please be a little more specific as to how I can save the grid file with the HK values in a format that can be read with a text editor such as wordpad. When I use the 3D Data Set -> Grid... in MODFLOW's LPF Package|Horizontal Hydraulic Conductivity window, it bundles the information into the .gpr file and I cant gain access to the information within this file except with the HDFView program.
Thanks once again for your help
