topoSet - Operates on cellSets/faceSets/pointSets through a dictionary.

Valid versions: OF Version 21.png

2 Synopsis

topoSet [OPTIONS]

3 Description

Operates on cellSets/faceSets/pointSets through a dictionary (by default system/topoSetDict). The results are stored in constant/polyMesh/sets

-dict FILE

Specify an alternative dictionary for the topoSet dictionary

-noSync

Do not synchronise selection across coupled patches

-noZero

Exclude the 0 directory from the times list

-time RANGES

Select time steps. RANGES follows the time selection rules

-latestTime

Apply only on the latest time available

-constant

Include the constant directory in the times list

-parallel

Run the utility in parallel

-roots "(DIR1 [...DIRN])"

Directories through which the data are distributed

-region NAME

Specify a mesh region by its NAME

-case DIR

Execute the command on the case directory DIR. If not provided, use the current directory

-noFunctionObjects

Skip the execution of the functionObjects

-help

Display the help and exit

4 topoSetDict description

The default dictionary is located in

/system/topoSetDict

Usually dictionaries created elsewhere have the extension .topoSet (i.e. myTopoSet.topoSet).


The dictionary looks like:

actions
(
  {
    name    selectedCells;
    type    cellSet;
    action  new;
    source  boxToCell;
    sourceInfo
    {
      box (x0 y0 z0) (x1 y1 z1);
    }
  }
  {
    name    selectedFaces;
    type    faceSet;
    action  new;
    source  patchToFace;
    sourceInfo
    {
      name bottomWall;
    }
  }
);
