Communicate and project the FieldsTags
to the next-coarser grid in the multigrid hierarchy.
FieldsTags | These tags will be communicated and projected. They can hold any type that works with apply_matrices and supports addition, e.g. Variables . |
OptionsGroup | The option group identifying the multigrid solver |
FieldsAreMassiveTag | A boolean tag in the DataBox that indicates whether or not the FieldsTags have already been multiplied by the mass matrix. This setting influences the way the fields are projected. In particular, the mass matrix already includes a Jacobian factor, so the difference in size between the parent and the child element is already accounted for. |
ReceiveTags | The projected fields will be stored in these tags (default: FieldsTags ). |
