3.6.7 Point Properties Specific to Matrix Fiber Injections

In a matrix fiber injection the starting points of the fibers are arranged in several rows having the shape of a rectangle or a parallelogram. Each row has the same distance to the previous and is divided into equal sections (see Figure  3.6.5).

You have to specify the coordinates of the starting point and the end of point of the first row and the coordinates where the last row should start. Click the Injection Point Properties tab in the Set Fiber Injection Properties dialog box (Figure  3.6.2). In the Points region, set the $x$, $y$, and $z$ coordinates in the x0, y0, and z0 fields for the starting point and the $x$, $y$, and $z$ coordinates in the x1, y1, and z1 fields for the end point of the first row of fibers. The $x$, $y$, and $z$ coordinates of the starting point of the last row have to be entered in the x2, y2, and z2 fields.

At each row, the number of fibers specified in the Point Density Edge1 field are injected. The number of rows to be injected is specified in Edge2.

You can double check the number of fibers computed in this fiber injection if you inspect the Numbers of Fibers Computed field.

Note that this fiber injection type is only available for 3D problems.
