ContainsPoint() [1/3]

bool Nektar::SpatialDomains::Geometry::ContainsPoint ( const Array< OneD, const NekDouble > &  gloCoord, Array< OneD, NekDouble > &  locCoord, NekDouble  tol  )

ContainsPoint() [2/3]

bool Nektar::SpatialDomains::Geometry::ContainsPoint ( const Array< OneD, const NekDouble > &  gloCoord, Array< OneD, NekDouble > &  locCoord, NekDouble  tol, NekDouble &  dist  )

inline

Determine whether an element contains a particular Cartesian coordinate \(\vec{x} = (x,y,z)\).

For curvilinear and non-affine elements (i.e. where the Jacobian varies as a function of the standard element coordinates), this is a non-linear optimisation problem that requires the use of a Newton iteration. Note therefore that this can be an expensive operation.

The parameter tol which is by default 0, can be used to expand the coordinate range of the standard element from \([-1,1]^d\) to \([-1-\epsilon,1+\epsilon\) to handle challenging edge cases. The function also returns the local coordinates corresponding to gloCoord that can be used to speed up subsequent searches.

Parameters

gloCoord	The coordinate \( (x,y,z) \).
locCoord	On exit, this is the local coordinate \(\vec{\xi}\) such that \(\chi(\vec{\xi}) = \vec{x}\).
tol	The tolerance used to dictate the bounding box of the standard coordinates \(\vec{\xi}\).
dist	On exit, returns the minimum distance between gloCoord and the quadrature points inside the element.

Returns

true if the coordinate gloCoord is contained in the element; false otherwise.

GetBoundingBox()

std::array< NekDouble, 6 > Nektar::SpatialDomains::Geometry::GetBoundingBox

(

)

Generates the bounding box for the element.

For regular elements, the vertices are sufficient to define the extent of the bounding box. For non-regular elements, the extremes of the quadrature point coordinates are used. A 10% margin is added around this computed region to account for convex hull elements where the true extent of the element may extend slightly beyond the quadrature points.

GetEdgeFaceMap()

int Nektar::SpatialDomains::Geometry::GetEdgeFaceMap ( int  i, int  j  ) const

inline

Returns the standard element edge IDs that are connected to a given face.

For example, on a prism, edge 0 is connnected to faces 0 and 1; GetEdgeFaceMap(0,j) would therefore return the values 0 and 1 respectively. We assume that j runs between 0 and 1 inclusive, since every face is connected to precisely two faces for all 3D elements.

This function is used in the construction of the low-energy preconditioner.

Parameters

i	The edge to query connectivity for.
j	The local face index between 0 and 1 connected to this element.

GetEdgeNormalToFaceVert()

int Nektar::SpatialDomains::Geometry::GetEdgeNormalToFaceVert ( int  i, int  j  ) const

inline

Returns the standard lement edge IDs that are normal to a given face vertex.

For example, on a hexahedron, on face 0 at vertices 0,1,2,3 the edges normal to that face are 4,5,6,7, ; so GetEdgeNormalToFaceVert(0,j) would therefore return the values 4, 5, 6 and 7 respectively. We assume that j runs between 0 and 3 inclusive on a quadrilateral face and between 0 and 2 inclusive on a triangular face.

This is used to help set up a length scale normal to an face

Parameters

i	The face to query for the normal edge
j	The local vertex index between 0 and nverts on this face

GetLocCoords()

NekDouble Nektar::SpatialDomains::Geometry::GetLocCoords ( const Array< OneD, const NekDouble > &  coords, Array< OneD, NekDouble > &  Lcoords  )

inline

Determine the local collapsed coordinates that correspond to a given Cartesian coordinate for this geometry object.

For curvilinear and non-affine elements (i.e. where the Jacobian varies as a function of the standard element coordinates), this is a non-linear optimisation problem that requires the use of a Newton iteration. Note therefore that this can be an expensive operation.

Note that, clearly, the provided Cartesian coordinate lie outside the element. The function therefore returns the minimum distance from some position in the element to . Lcoords will also be constrained to fit within the range \([-1,1]^d\) where \( d \) is the dimension of the element.

Parameters

coords	Input Cartesian global coordinates
Lcoords	Corresponding local coordinates

Returns

Distance between obtained coordinates and provided ones.

This function is used in the construction of the low-energy preconditioner.

Parameters

i	The vertex to query connectivity for.

bool Nektar::SpatialDomains::Geometry::v_ContainsPoint ( const Array< OneD, const NekDouble > &  gloCoord, Array< OneD, NekDouble > &  locCoord, NekDouble  tol, NekDouble &  dist  )

protectedvirtual

Determine whether an element contains a particular Cartesian coordinate \(\vec{x} = (x,y,z)\).

For curvilinear and non-affine elements (i.e. where the Jacobian varies as a function of the standard element coordinates), this is a non-linear optimisation problem that requires the use of a Newton iteration. Note therefore that this can be an expensive operation.

The parameter tol which is by default 0, can be used to expand the coordinate range of the standard element from \([-1,1]^d\) to \([-1-\epsilon,1+\epsilon\) to handle challenging edge cases. The function also returns the local coordinates corresponding to gloCoord that can be used to speed up subsequent searches.

Parameters

gloCoord	The coordinate \( (x,y,z) \).
locCoord	On exit, this is the local coordinate \(\vec{\xi}\) such that \(\chi(\vec{\xi}) = \vec{x}\).
tol	The tolerance used to dictate the bounding box of the standard coordinates \(\vec{\xi}\).
dist	On exit, returns the minimum distance between gloCoord and the quadrature points inside the element.

Returns

true if the coordinate gloCoord is contained in the element; false otherwise.

Returns the standard element edge IDs that are connected to a given face.

For example, on a prism, edge 0 is connnected to faces 0 and 1; GetEdgeFaceMap(0,j) would therefore return the values 0 and 1 respectively. We assume that j runs between 0 and 1 inclusive, since every face is connected to precisely two faces for all 3D elements.

This function is used in the construction of the low-energy preconditioner.

Parameters

i	The edge to query connectivity for.
j	The local face index between 0 and 1 connected to this element.

v_GetEdgeNormalToFaceVert()

protectedvirtual

Returns the standard lement edge IDs that are normal to a given face vertex.

For example, on a hexahedron, on face 0 at vertices 0,1,2,3 the edges normal to that face are 4,5,6,7, ; so GetEdgeNormalToFaceVert(0,j) would therefore return the values 4, 5, 6 and 7 respectively. We assume that j runs between 0 and 3 inclusive on a quadrilateral face and between 0 and 2 inclusive on a triangular face.

This is used to help set up a length scale normal to an face

Parameters

i	The face to query for the normal edge
j	The local vertex index between 0 and nverts on this face

v_GetLocCoords()

NekDouble Nektar::SpatialDomains::Geometry::v_GetLocCoords ( const Array< OneD, const NekDouble > &  coords, Array< OneD, NekDouble > &  Lcoords  )

protectedvirtual

Determine the local collapsed coordinates that correspond to a given Cartesian coordinate for this geometry object.

For curvilinear and non-affine elements (i.e. where the Jacobian varies as a function of the standard element coordinates), this is a non-linear optimisation problem that requires the use of a Newton iteration. Note therefore that this can be an expensive operation.

Note that, clearly, the provided Cartesian coordinate lie outside the element. The function therefore returns the minimum distance from some position in the element to . Lcoords will also be constrained to fit within the range \([-1,1]^d\) where \( d \) is the dimension of the element.

Parameters

coords	Input Cartesian global coordinates
Lcoords	Corresponding local coordinates

Returns

Distance between obtained coordinates and provided ones.

ValidateRegGeomFactor()

GeomFactorsSharedPtr Nektar::SpatialDomains::Geometry::ValidateRegGeomFactor ( GeomFactorsSharedPtr  geomFactor )

staticprotected

Check to see if a geometric factor has already been created that contains the same regular information.

The principle behind this is that many regular (i.e. constant Jacobian) elements have identicial geometric factors. Memory may therefore be reduced by storing only the unique factors.

Parameters

geomFactor

The GeomFactor to check.

Returns

Either the cached GeomFactor or geomFactor.

Todo:

Currently this method is disabled since the lookup is very expensive.
