Binding change operators enable conversion of values from one entity to another related entity. When performing binding changes, it may be necessary to specify how the values will be aggregated, and depending upon the source value type (scalar, vector, or tensor), only a subset of aggregation modes are valid. Min, max, and extreme aggregation modes are applicable to real scalar values only.
Aggregation Mode

|
Applies To
|
average
|
Sum of values divided by the number of values.
|
scalar, vector, tensor
|
sum
|
Total of values.
|
scalar, vector, tensor
|
min
|
Minimum value.
|
scalar
|
max
|
Maximum value.
|
scalar
|
extreme
|
Value with the largest absolute value (with sign).
|
scalar

The Model Library contains the following Binding Change operators:
Aggregates nodal values to elemental values.
Inputs
|
src: a nodal value table.
elems: an element entity table.
aggregate: an aggregation mode (avg, sum, min, max, extreme).
|
Outputs
|
answer: an elemental value table.
|
Notes
|
| • | If src is a vector or tensor table, it should be transformed to the global coordinate system. |
| • | min, max, and extreme aggregate modes are valid only for scalar data. |

| • | The XML example below does not specify layer_idx or layer_label and uses the defaults. |
| • | The Expression Builder will provide default values for layer_idx and layer_label. |
