foamPostProcess
Description
Execute the set of functionObjects specified in the selected dictionary
(which defaults to system/functions) or on the command-line for the
selected set of times on the selected set of fields.
The functionObjects are either executed directly or for the solver
optionally specified as a command-line argument.
Usage
\b foamPostProcess [OPTION]
- \par -dict <file>
Read functions dictionary from specified location
- \par -solver <name>
Solver name
- \par -libs '(\"lib1.so\" ... \"libN.so\")'
Specify the additional libraries loaded
-\par -region <name>
Specify the region
- \par -func <name>
Specify the name of the functionObject to execute, e.g. Q
- \par -funcs <list>
Specify the names of the functionObjects to execute, e.g. '(Q div(U))'
- \par -field <name>
Specify the name of the field to be processed, e.g. U
- \par -fields <list>
Specify a list of fields to be processed,
e.g. '(U T p)' - regular expressions not currently supported
- \par -time <ranges>
comma-separated time ranges - eg, ':10,20,40:70,1000:'
- \par -latestTime
Select the latest time
- \par -list
List the available configured functionObjects
- \par -list
List the available functionObject templates
Example usage:
- Print the list of available configured functionObjects:
\verbatim
foamPostProcess -list
\endverbatim
- Execute the cellMax function on the pressure field in the default
region for all the available times:
\verbatim
foamPostProcess -func 'cellMax(p)'
\endverbatim
- Execute the functionObjects specified in the functions dictionary of the
'cooling' region using the 'fluid' solver for the latest time only:
\verbatim
foamPostProcess -region cooling -solver fluid -latestTime
\endverbatim
