T2ext
T2ext, written by Jerry Fairley, is a PERL script to extract data from TOUGH2-MP file OUTPUT_DATA. Regardless of the dimensionality of the simulation, the output from T2ext is a space-delimited four or six column file, each line of which gives X,Y,Z,P (for a primary variable) or X,Y,Z,Fx,Fy,Fz (for a secondary variable). Users of GMT (Generic Mapping Tools) will find the output from T2ext is conveniently formatted for plotting with that program. Run T2ext -h for a description of all available options.
