};Description
DVclamp transforms the values in one component of a Cell_Data object as follows: If above is set, then any value above max_value is set to max_value. If below is set, then any value below min_value is set to min_value. Otherwise, the values are not changed.If both above and below are on, then the output field's selected component values are all in this range:min_value <= value <= max_valueNull data values are not affected.
Input
A reference to an input field that contains a Cell_Data object. The field's data components can be scalar or vector.
An integer. If the value is not 0, the field's minimum and maximum data values are reset to post-clamping values.
Output
A new mesh of Cell_Data that contains the clamped output component. It has the same data type as the input Cell_Data.
