Defines

PVEC_REAL_MPI_TYPE#: MPI type of BoutReal for communications.

Variables

const int IN_SENT_UP = 0#: Data lower in X than branch-cut, at upper boundary in Y.

const int OUT_SENT_UP = 1#: Data higher in X than branch-cut, at upper boundary in Y.

const int IN_SENT_DOWN = 2#: Data lower in X than branch-cut, at lower boundary in Y.

const int OUT_SENT_DOWN = 3#: Data higher in X than branch-cut, at lower boundary in Y.

const int IN_SENT_OUT = 4#: Data going in positive X direction (in to out)

const int OUT_SENT_IN = 5#: Data going in negative X direction (out to in)

namespace bout

Provides access to the Hypre library, handling initialisation and finalisation.

Usage

#include <bout/hyprelib.hxx>

class MyClass { public:

private: HypreLib lib; };

This will then automatically initialise Hypre the first time an object is created, and finalise it when the last object is destroyed.
