Inlet
Use the Inlet node to release grains into the modeling domain from selected boundaries. The released grains are positioned such that their centers lie on the selected boundaries. The selected boundaries are not included in the grain–wall interactions.
See Release for information about the following sections: Release Times, Released Grain Properties, Initial Value of Auxiliary Dependent Variables, and Advanced Settings.
Initial Values
See the Release node for information about Velocity, Angular velocity in body-fixed frame and Temperature.
Position
Select an option from the Position list: Random (the default), Density, or Uniform distribution (2D components), or Projected plane grid (3D components). Density, and Random have the same settings as described for the Release node.
•
For 2D components, if Uniform distribution is selected, the union of the selected edges is divided into N segments of approximately equal length, and a grain is placed in the middle of each segment. Here, N refers to the total number of grains being attempted per release time.
•
For 3D components, if Projected plane grid is selected, the grains are distributed on a plane grid in planes that are approximately tangential to the selected boundaries.
