Add Scalar Injection¶
Introduction¶
This functionality allows users to define custom injections with local species concentrations or injection rates that differ from those defined on the particle parent. Whereas children geometry attached to the scalar parent inherit the characteristics defined by the parent, scalar injections allow for differentiated characteristics within a particle family.
Scalar injections can have children geometry that localize the action of the injection region to specific regions of the simulation domain. Since the scalar injection is a child to the particle parent, any children geometry attached to the scalar injection region can be conceptualized as grandchildren to the scalar parent. These grandchildren geometry do not inherit their properties from the grandparent scalar family—they inherit properties from their parent (which in this case is the scalar injection region).
In the example below, a single scalar parent contains two distinct injection regions. We use two injection regions to introduce two addition streams with distinct concentrations. Each injection region has a single child. TBD
Access¶
When you select Add Scalar Injection on the context-specific toolbar, a new Add Geometry window will launch, and after you select your specifications, the property grid below will appear.
