Particle Injection dialog box (Flow/ESC/Multiphysics)

Name
Name	Sets a name for the simulation object.Description opens an editor that lets you type a description for the simulation object.
Destination Folder
Simulation Object Container	Specifies the folder in the Simulation Navigator in which the boundary condition will be stored. The list includes the root container and existing folders that you created using the New Folder command. Examples of a root container include Load Container, Constraint Container, and Simulation Object Container.
Folder Manager	Displays a hierarchical listing of existing folders. To create a new folder, right-click any level of the hierarchy and choose New Folder.
Region
Group Reference	Applies the boundary condition to the selected group. For more information, see Group Reference options.
Select Object	Lets you select the faces or elements to define the Particle Injection region. The selection must contain only fluid element free faces, not embedded faces.Excluded lets you remove individual entities from within your selected object.
Stacked Smart Selector Methods	Opens the Smart Selector Methods dialog box where you can specify a progression of smart selection filters.For more information, see Smart Selector Methods dialog box.
Parameters
Mass and Size Options	Lets you specify particles' mass and size in the Mass and Diameter boxes, and drag properties in the Drag list, which are used in the equation of motion of each particle.Drag specifies how the software models particle drag.Spherical CorrelationComputes the particle drag coefficient using the Reynolds number.SpecifyUses the drag coefficient that you specify in the Drag Coefficient box.Clear this option to model massless particles with zero size, which follow the flow field.
Inflow Density	Specifies the density of particles that are injected into the fluid domain.Mass per VolumeDefines the total mass of particles that are injected per volume of fluid. You specify the value in the Mass per Volume box. This option requires that you specify mass of particles.Mass per Unit TimeDefines the total mass of particles per unit of time that are injected with the fluid entering the domain. You specify the value in the Mass per Unit Time box. This option requires that you specify mass of particles.Number per VolumeDefines the total number of particles that are injected per volume of fluid. You specify the value in the Number per Volume box.Number per SecondDefines the total number of particles per second that are injected with the fluid entering the domain. You specify the value in the Number per Second box.
Injection Velocity	Available when Inflow Density is set to Mass per Second or Number per Second.Specifies the particle injection velocity.Same as FluidSets the injection velocity as identical to the fluid velocity at the injection site.Specify Normal VelocitySets the initial velocity normal to the inflow plane of the injected particles entering the fluid domain. You specify the value in the Initial Velocity box.
