Field distributed over a level: decomposition (BoxArray) + distribution (DistributionMapping) + ncomp...

Definition multifab.hpp:33

pops::System

Coupled multi-species system, composed at runtime from generic bricks.

Definition system.hpp:89

pops::CoupledSourceFor

Concept: C is a valid coupling source for System if System is a CoupledSystem and if C exposes apply(...

Definition coupled_source.hpp:24

pops::CoupledSystemLike

Minimal concept for coupled systems: n_blocks and for_each_block with a named functor.

Definition coupled_system.hpp:84

coupled_system.hpp

CoupledSystem: heterogeneous collection of equation blocks (multi-species, multi-scheme).

multifab.hpp

MultiFab: a field DISTRIBUTED over a level (equivalent of AMReX's MultiFab).

Definition amr_hierarchy.hpp:29

pops::Real

double Real

Definition types.hpp:30

pops::NoCoupledSource

NULL coupling source (default): apply() is a no-op.

Definition coupled_source.hpp:32

pops::NoCoupledSource::apply

void apply(System &, const MultiFab &, Real) const

Definition coupled_source.hpp:34

types.hpp

Base scalar types and the POPS_HD macro (host+device portability).
