Defining Cell Clusters
To reproduce the zones defined in the gPROMS network model, you group the Simcenter STAR-CCM+ mesh cells into clusters based on their position.
- Right-click the Select Models... node and select
- Activate the Coordinate Cell Clustering model.
To create the cell clusters, you define a cutting template by specifying
the number of divisions along each axis of a coordinate system. As the spray dryer
has cylindrical symmetry, it is convenient to use cylindrical coordinates. To create
a cylindrical coordinate system:
- Expand the node.
-
Right-click the Local Coordinate Systems node and select .
The default orientation is appropriate.
- In the Create Coordinate System dialog, accept the default settings by clicking Create and Close.
In this simulation, you create 27 clusters by specifying 3
divisions along each axis of the cylindrical coordinate system:
-
Expand the
node.The Cluster Merging Threshold value is appropriate. This property defines a threshold value for merging clusters that have small volumes with adjacent clusters.
- Right click the Clustering Criteria node, and select .
-
Select the Clustering Criterion node, and set the
Coordinate System to .
The default number of divisions ([3, 3, 3]) is acceptable.
To divide the mesh into clusters, you run the
Coordinate Cell Clustering solver for one
iteration:
-
Click
(Step).
To visualize the clusters in a scalar scene:
- Create a scalar scene named Cell Clusters.
-
Expand the
node and set the following properties:
