class FieldPerp : public Field

#include <fieldperp.hxx>

Represents a 2D field perpendicular to the magnetic field at a particular index in Y, which only varies in X-Z.

Primarily used inside field solvers

Public Functions

FieldPerp::FieldPerp(Mesh * fieldmesh = nullptr, CELL_LOC location_in = CELL_CENTRE, int yindex_in = -1, DirectionTypes directions_in = {YDirectionType::Standard, ZDirectionType::Standard})

Constructor

FieldPerp(const FieldPerp &f)

Copy constructor. After this the data will be shared (non unique)

FieldPerp(FieldPerp &&rhs)

Move constructor

FieldPerp(BoutReal val, Mesh *localmesh = nullptr)

Constructor. This creates a FieldPerp using the global Mesh pointer (mesh) allocates data, and assigns the value val to all points including boundary cells.

~FieldPerp()

FieldPerp &operator=(const FieldPerp &rhs)

Assignment operators

FieldPerp &operator=(FieldPerp &&rhs)

FieldPerp &operator=(BoutReal rhs)

const Region<IndPerp> &getRegion(REGION region) const

Return a Region<IndPerp> reference to use to iterate over this field.

const Region<IndPerp> &getRegion(const std::string &region_name) const

int getIndex() const

Returns the y index at which this field is defined

FieldPerp &setIndex(int y)

Sets the y index at which this field is defined

This is used in arithmetic operations

FieldPerp &setLocation(CELL_LOC location)

FieldPerp &allocate()

Ensure that data array is allocated and unique

bool isAllocated() const

True if the underlying data array is allocated.

const BoutReal *operator[](int jx) const

BoutReal *operator[](int jx)

Returns a C-style array (pointer to first element) in Z at a given X index. Used mainly for FFT routines

BoutReal &operator()(int jx, int jz)
