This is the EquationSystems class.
virtual std::unique_ptr< Partitioner > & partitioner()
A partitioner to use at each partitioning.
The Mesh class is a thin wrapper, around the ReplicatedMesh class by default.
Manages consistently variables, degrees of freedom, and coefficient vectors.
unsigned int add_variable(std::string_view var, const FEType &type, const std::set< subdomain_id_type > *const active_subdomains=nullptr)
Adds the variable var to the list of variables for this system.
