Particles
This options is available only for MODFLOW 2000-GWT and MOC3D.
To show or hide particles
- Click the Show menu and select Particles. This
alternately shows or hides the particles.
- Particles are displayed as small cubes. Showing all particles in the grid may result in a very cluttered picture.
To avoid this, particles may be limited by cropping and thresholding. The figure below
shows particles in the top portion of a grid.
(How to control
particles display)

- Each particle is colored according to the solute concentration associated with the particle.
The color is determined by mapping the concentration to the color bar.
- Cropping may be applied to show only
those particles in a specified subregion of the grid.
- Thresholding may be applied to show only
those particles having concentrations within a specified range.
