File/Write/Surface Clusters... menu item is used to save view factor and surface cluster parameters for the surface-to-surface radiation model. It opens the
View Factor and Cluster Parameters panel.
View Factor and Cluster Parameters Panel
View Factor and Cluster Parameters panel allows you to set parameters related to surface clusters and view factors for the surface-to-surface radiation model. See Section
13.3.12 for information about using this panel.
contains parameters for creating surface clusters.
Faces per Surface Cluster for Flow Boundary Zones
specifies the number of faces in each surface cluster for flow boundary zones. The default is set to
1. See Section
13.3.7 for details about clustering.
Apply to All Walls
applies the value specified in the
Faces per Surface Cluster for Flow Boundary Zones field to all wall zones adjacent to fluid zones.
View Factor Parameters
contains parameters for computing view factors.
specifies the geometric orientation of surface pairs with respect to each other.
specifies that there is another surface blocking the views between the surfaces under consideration.
specifies that there is no obstruction between the surfaces under consideration.
specifies whether or not smoothing should be performed on the view factor matrix. See Section
13.3.7 for details about smoothing.
specifies that the view factor matrix will not be smoothed.
specifies that the least-squares method will be used for smoothing the view factor matrix.
specifies the method for computing view factors. See Section
13.3.12 for information about choosing a method.
specifies the use of the adaptive method for computing the view factors.
specifies the use of the hemicube method for computing the view factors. The hemicube method is available only for 3D cases.
contains parameters related to the hemicube method for computing view factors. These inputs are available only when
Hemicube is selected under
Method. See Section
13.3.12 for information about setting hemicube parameters.
specifies the resolution of the hemicube. The default value is set to
10. You can increase the value to reduce aliasing effects that can lead to overestimated or underestimated view factors.
specifies the number of subfaces into which each face is divided. The default value is set to
Normalized Separation Distance
specifies the ratio of the minimum face separation to the effective diameter of the face. The default value is set to
