Generate Particles at Selected Cells

Module|Menu|Command: 3D Grid | MODPATH | Generate Particles at Selected Cells...
(This command is only available if a MODFLOW CCF solution generated by MODFLOW 2000 exists, and you have 3D grid cells selected.)

This command opens the Generate Particles dialog, and when you select OK, particles are created in all the selected cells according to the options specified.

Number of Particles

If the More options toggle is not selected, you can use the slider to change the number of particles created per cell.  The minimum is 1, and the maximum depends on the option being used to distribute the particles.  The number of particles jumps as the slider is moved in order to create an even distribution of particles.

If the More options toggle is selected, the slider is not available, and the user has more control over the total number of particles and how they are distributed.

Distribute Particles

There are three options for distributing the particles within the selected cells.

Within Cell

With this option, the particles are distributed in the interior of the cells.

On Cell Faces

With this option, the particles are distributed on the faces of the cells.

Distribute Starting Points on Water Table Surface

With this option, the particles are restricted to the top face only. When using this option, you should be sure to select the cells corresponding to the location of the water table surface.

More Options

The More options toggle expands the dialog, allowing you to further define how particles are distributed within the selected cells.
