- MT3DMS: The primary result of MT3DMS is concentration. The specices number and
simulation time, from which the result is read, can be selected from the Species Number
and Total Elapsed Time drop-down boxes. These drop-down boxes are empty, if
simulation results do not exist.
- Save... and Read: To extract a certain result type, simply click the Read button. You may
save the contents of the spreadsheet by clicking the Save... button and specifying the file
name and the file type in a Save Matrix As... dialog box. There are four file types, ASCII
Matrix (Warp form), ASCII Matrix, SURFER files and SURFER files (real-world). An ASCII
Matrix file may be loaded into the spreadsheet at a later time. The format of the ASCII
matrix file is described in Appendix 2. A SURFER file has three columns containing the (x,
y) coordinates and the value of each cell. If the file type is SURFER files, the origin of the
coordinate system for saving the file is set at the lower-left corner of the model grid. If the
file type is SURFER files (real-world), the real-world coordinates of each cell will be saved.
The real-world coordinate system is defined by Options < Environment (section 3.9).
- Apply: The Apply button appears only if you start the Result Extractor from the Data
Editor via Value
