| bool | operator== (const SubcellOptions &lhs, const SubcellOptions &rhs) |
Holds the system-agnostic subcell parameters, such as numbers controlling when to switch between DG and subcell.
| evolution::dg::subcell::SubcellOptions::SubcellOptions | ( | const SubcellOptions & | subcell_options_with_block_names, |
| const DomainCreator< Dim > & | domain_creator | ||
| ) |
Given an existing SubcellOptions that was created from block and group names, create one that stores block IDs.
The DomainCreator is used to convert block and group names into IDs and also to check that all listed block names and groups are in the domain.
