The variables, in the order of appearance on the line, are defined as:
1. Particle index number: The index number is positive, if the forward particle tracking scheme
is used. A negative index number indicates that the backward particle tracking scheme is
used.
2. Global coordinate in the x-direction.
3. Global coordinate in the y-direction.
4. Verticle local coordinate within the cell
5. Global coordinate in the z-direction
6. Cumulative travel time.
7. J index of cell containing the point.
8. I index of cell containing the point.
9. K index of cell containing the point.
Except the particle index number, this format is identical to the PATHLINE FILE format
described in the documentation of MODPATH.
Hydraulic heads
To save the hydraulic heads in the current layer at the current stress period and time step, select
Save Heads As... from the File menu. PMPATH saves the hydraulic heads in ASCII Matrix
format (see Appendix 2).
Drawdowns
To save drawdowns in the current layer, choose Save Drawdowns As... from the File menu and
specify a file name in the standard File Save As dialog box. This menu item is disabled, if the
drawdown file DDOWN.DAT is not available. PMPATH saves the drawdowns in the ASCII
Matrix format (see Appendix 2).
Flow velocities
To save flow velocities in the current layer, choose Save Velocity As... from the File menu and
specify a file name in the standard File Save As dialog box. Average pore velocities at the center
of each cell are saved in the ASCII Matrix format (see Appendix 2). In addition, the velocity
components along the I-, J- and K-axes are added to the end of the file. The default velocity at
30
inactive cells is 1.0×10 .
