This section details the various ways options for placing and displacing particles during model development
and simulation. The four options for placing particles includes:

• placing particles around a well feature (see subsection 4.3.2)
• drawing a rectangle filled with evenly-space particles
• drawing a polygon with evenly-spaced particles
• placing particles along a polyline

The ‘ParticleTK’ button along the left-side of the MAGNET Modeling Environment
(see Section 2.5) provides access to the tools need to place particles. Click on it to
bring up the Particle pop-up menu (see Figure 5-17). Each tool is discussed in the following subsections.

Figure 5-17: Particle Pop-up menu.

As mentioned in subsection 4.3.2, options for displaying particles are available in the Default Model
Parameters and Options menu.

5.6.1 Particles along a Polyline

Select ‘ParticleLine’ from the Particle pop-up menu to place particles along a polyline. The cursor will
become a cross-hair, allowing for placement of polyline vertices with single-clicks of the LM button. The
polyline will appear as a series of bright yellow line segments with circles at the vertex locations (see Figure
5-18). The location can of any vertex can be changed by hovering the mouse over it and click-dragging to
the new desired location. Once the last vertex has been placed, LM click the ‘SaveShape’ button to finalize
the polyline.

Run the model forward to perform forward
particle tracking, or run the model backward
for reverse particle tracking (see subsection
5.1.3 for details on running the model forward
or backward). Note that if a particle feature is
already present in the model before submitting
for simulation, a prompt will help to determine
if forward or backward particle tracking will be
performed (see right).
