Coordinate Cell Clustering Model Reference

The Coordinate Cell Clustering model allows you to divide the mesh into groups of cells, called clusters, based on each cell's position within a clustering template. You create the clustering template by specifying the number of divisions along each axis of a specified coordinate system.

Coordinate Cell Clustering Solver

Cluster Merging Threshold
Defines a threshold value for merging clusters that have small volumes. If the volume percentage of a cell cluster (relative to the volume of the entire continuum) is below the specified threshold value, the cell cluster is merged with an adjacent cell cluster.
Solver Frozen
When On, the solver does not update any quantity during an iteration. It is Off by default. This is a debugging option that can result in non-recoverable errors and wrong solutions due to missing storage. See Finite Volume Solvers Reference for details.

Clustering Criterion Properties

Coordinate System
Specifies the coordinate system with respect to which you define the cell cluster subdivisions.
Subdivisions (for Subdivisions option only)
Defines the number of divisions along each axis of a specified coordinate system, in the format [#1, #2, #3], where #i denotes the number of divisions for axis i.
Control Point on First Axis (for Control Points option only)
Specify a vector list of control point divisions along the axis, for example, [0, 10, 15, 25, 35, 55, 90,100]. The vector list need not contain actual measured distances — Simcenter STAR-CCM+ normalizes the list according to the bounding dimensions of the domain in the axis direction. As a minimum the list must contain the first and last control point locations which by default are 0 and 1 (corresponding to no divisions). Any points not in order are ordered automatically.
Control Point on Second Axis (for Control Points option only)
As for the Control Point on First Axis but for the second axis.
Control Point on Third Axis (for Control Points option only)
As for the Control Point on the First Axis but for the third axis.

Field Functions

Cell Cluster Index
Simcenter STAR-CCM+ identifies each cell cluster with a unique index. You can use this field function to:
  • visualize the clusters in a scalar scene
  • create threshold derived parts or cell-sets that can then be used in reports
