Description
Calculates the spatial minimum and maximum extents of a field
The extents are derived from the bound box limits after identifying
the locations where field values exceed the user-supplied threshold
value.
Usage
Example of function object specification:
fieldExtents1
{
type fieldExtents;
libs ("libfieldFunctionObjects.so");
...
writeToFile yes;
log yes;
fields (alpha);
threshold 0.5;
patches ();
}
Where the entries comprise:
Property | Description | Required | Default
type | type name: fieldExtents | yes |
writeToFile | write extents data to file | no | yes
log | write extents data to standard output | no | yes
internalField | Process the internal field | no | yes
threshold | Field value to identify extents boundary | yes |
referencePosition | Reference position | no | (0 0 0)
fields | list of fields to process | yes |
patches | list of patches to process | no | <all>
Output data is written to the file \<timeDir\>/fieldExtents.dat
Note
For non-scalar fields, the magnitude of the field is employed and
compared to the threshold value.
