bool Nektar::SpatialDomains::Geometry::ContainsPoint ( const Array< OneD, const NekDouble > &  gloCoord,
Array< OneD, NekDouble > &  locCoord,
NekDouble  tol,
NekDouble resid 
)
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
gloCoordThe coordinate \( (x,y,z) \).
locCoordOn exit, this is the local coordinate \(\vec{\xi}\) such that \(\chi(\vec{\xi}) = \vec{x}\).
tolThe tolerance used to dictate the bounding box of the standard coordinates \(\vec{\xi}\).
residOn 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
iThe edge to query connectivity for.
jThe local face index between 0 and 1 connected to this element.

◆ 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
coordsInput Cartesian global coordinates
LcoordsCorresponding local coordinates
Returns
Distance between obtained coordinates and provided ones.

)
protectedvirtual

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
gloCoordThe coordinate \( (x,y,z) \).
locCoordOn exit, this is the local coordinate \(\vec{\xi}\) such that \(\chi(\vec{\xi}) = \vec{x}\).
tolThe tolerance used to dictate the bounding box of the standard coordinates \(\vec{\xi}\).
residOn 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.
