Alternate Value Specification Reference

Data is not mapped to target points that fail the proximity or normalcy checks. Choose to assign constant alternate values for each field to these points. Specify the alternate value in the properties of the Target Specifications > Surface/Volume > Alternate Value Specification node. The field functions you selected for mapping populate the relevant property fields of the Alternate Values Specification node.

Note Be careful while specifying alternate values. In Simcenter STAR-CCM+, the order of the values is tied to the order in which the selected fields are listed. This rule applies to both scalar and vector alternate values.
Table 1. Properties
Selected Scalar Fields This read-only property lists the scalar fields for mapping.
Scalar Alternate Values Enter an alternate value for each of the chosen scalar fields to be assigned to target points that are not mapped. Enter the constant values for all the functions as a comma-separated list in the same order as the selected field functions. Place the entire list in square brackets. This property is relevant only if the proximity check (or normalcy check for the surface mapper) option is activated. See Defining Constraint Checks.
Selected Vector Fields This read-only property lists the scalar fields for mapping.
Vector Alternate Values Enter an alternate value in vector notation for each of the chosen vector fields to be assigned to target points that are not mapped. Enter the three components of each function as a comma-separated list contained in round brackets. List all the functions as a comma-separated list in the same order as the selected field functions. Place the entire list in square brackets. This property is relevant only if the Proximity Check (or Normalcy Check for the surface mapper) option is activated. See Defining Constraint Checks.
Estimate Alternate Values Controls whether to estimate an alternate value for unmapped targets. These options only appear for target surfaces.
Do Not Estimate Alternate Values The specified alternate values are used.
Estimate For All Unmapped Patches An alternate value is estimated by averaging the surrounding mapped targets. If this fails, the specified alternate values are used.
Max. Patch Face Area An alternate value is estimated by averaging the surrounding mapped targets, limited to a maximum patch area. A Maximum Unmapped Patch Area subnode is created. If this mapping fails, the specified alternate values are used.
Max. Patch Face Count An alternate value is estimated by averaging the surrounding mapped targets, limited to a specified number of surrounding faces. A Maximum Unmapped Face Count subnode is created. If this fails, the specified alternate values are used.
