A topoSetCellSource to select cells based on volScalarField values, i.e. select cells with given field value of >= min and <= max.


Operand Type Location
input volScalarField $FOAM_CASE/<time>/<inpField>
output cellSet $FOAM_CASE/constant/polyMesh/sets/<set>


Example of the fieldToCell topoSet by using actions sub-dictionary in system/topoSetDict file:

    // Mandatory (inherited) entries
    name        <name>;
    type        cellSet;
    action      <action>;

    // Mandatory entries
    source      fieldToCell;
    field       <fieldName>;
    min         <minFieldValue>;
    max         <maxFieldValue>;

where the entries mean:

Property Description Type Required Default
name Name of cellSet word yes -
type Type name: cellSet word yes -
action Action applied on cells - see below word yes -
source Source name: fieldToCell word yes -
field Name of volScalarField to use word yes -
min The min value for the subset scalar yes -
max The max value for the subset scalar yes -

Options for the action entry:

new      | Create a new cellSet from selected cells
add      | Add selected cells into this cellSet
subtract | Remove selected cells from this cellSet
