ASCII Matrix File
An ASCII Matrix file can be saved or loaded by the Browse Matrix dialog box (see section 3.8). The Results
Extractor, Field Interpolator and Field Generator use this file format to save the generated data.
File Format
1. Data: NCOL NROW
2. Data: MATRIX (NCOL, NROW)
Explanation of Fields Used in Input Instructions
ALL DATA IN THE SAME RECORD ARE SEPARATED BY A COMMA OR BLANK.
NCOL is the number of model columns.
NROW is the number of model rows.
MATRIX is a two dimensional data matrix saved row by row. Matrix can be saved in free format. If the wrap
from is used to save the matrix, each line of the matrix contains up to 20 values.
Example
If NCOL=6 and NROW=5, an ASCII Matrix file would be
6 5
121 152 133 144 315 516
221 252 233 244 215 216
321 352 333 344 315 316
421 452 433 444 415 416
521 552 533 544 515 516
Or
6 5
121 152 133 144 315 516 221 252 233 244 215 216
321 352 333 344 315 316 421 452 433 444 415 416
521 552 533 544 515 516
Boreholes file
A borehole file can be saved or loaded by the Boreholes and Observations dialog box (see section 3.5).
File Format
1. Data: LABEL
2. Data: NB XXX XXX XXX XXX
(The following data repeats NB times)
3. Data: ACTIVE X Y LAYER DRAW COLOR NAME
Explanation of Fields Used in Input Instructions
ALL DATA IN THE SAME RECORD ARE SEPARATED BY A COMMA OR BLANK.
LABEL is the file label. It must be PMWIN5000_BOR_FILE
NB is the number of boreholes. Maximum number of NB is 1000.
XXX reserved.
ACTIVE A borehole is active, if Active = 1.
X is the x-coordinate of the borehole.
Y is the y-coordinate of the borehole.
LAYER is the layer number of the borehole.
DRAW If DRAW = -1, the obervation vs. time curve of a borehole will be shown when the Graphs Viewer
is activated.
