Define the grid resolution that should be used when calculating fields in the background.
A fine grid produces the most accurate results, but might be slow for big molecules. A coarse grid does not look as good, but will be much faster for big molecules.
When you change the Grid choice, the fields that have already been calculated may be recalculated. If you have more than one field already present, ADFview will ask you to confirm that you indeed wish to recalculate the fields already present. Whatever you choose, the Grid setting will always apply for newly calculated fields.
