Computes the magnitude or magnitude squared of the Eulerian time derivative of an input volume field for time-variant simulations (not appropriate to steady-state simulations).
The result can be further used for determining e.g. variance or RMS values.
Operands:
| Operand | Type | Location |
|---|---|---|
input | vol<Type>Field | $FOAM_CASE/<time>/<inpField> |
output file | - | - |
output field | vol<Type>Field | $FOAM_CASE/<time>/<outField> |

where the entries mean:
| Property | Description | Type | Req'd | Dflt |
|---|---|---|---|---|
type | Type name: ddt2 | word | yes | - |
libs | Library name: fieldFunctionObjects | word | yes | - |
fields | Names of the operand fields | wordList | yes | - |
mag | Compute 'mag' instead of 'magSqr' | bool | no | false |
result | Name of results | word | no | magSqr(ddt2(@)) |
The inherited entries are elaborated in:
A list of fields can contain exact names or regular expressions. The token '@@' in the result name is replaced by the name of the source field. In the special case of a single source field (specified as a non-regex), the '@@' token checking is suppressed.
The function object will skip over fields that appear to have already been processed (ie, their names are similar to the output names).
Usage by the postProcess utility is not available.
