Copies the value stored in a given property from a given source grid to a given destination grid.
- Template Parameters
-
| attr_sc | Index of property that contains the value that should be copied. |
| attr_ds | Index of property to which the value should be copied to. |
| grid_source_type | Template type of the source grid grid_sc. |
| grid_dest_type | Template type of the destination grid grid_ds. |
- Parameters
-
| grid_sc | OpenFPM grid from which value is copied (source). |
| grid_ds | OpenFPM grid to which value is copied to (destination). |
| include_ghost | Bool variable that defines if the copying should include the ghost layer. False, if not; true, if yes. Default: false. |
