v_InitObject()

void Nektar::GlobalMapping::Mapping::v_InitObject ( const Array< OneD, MultiRegions::ExpListSharedPtr > &  pFields, const TiXmlElement *  pMapping  )

This function initialises the Mapping object. It computes the coordinates and velocity coordinates, initialises the workspace variables, and calls UpdateGeomInfo, which will perform the calculations specific for each type of Mapping.

Parameters

pFields	ExpList array used in the mapping
pMapping	xml element describing the mapping

VelocityLaplacian()

GLOBAL_MAPPING_EXPORT void Nektar::GlobalMapping::Mapping::VelocityLaplacian ( const Array< OneD, Array< OneD, NekDouble > > &  inarray, Array< OneD, Array< OneD, NekDouble > > &  outarray, const NekDouble  alpha = 0.0  )

inline

Generalised (correction to the) velocity Laplacian operator.

This function is used to calculate a correction defined as the difference between the generalised Laplacian and the original Laplacian multiplied by a constant \(\alpha\), resulting in

\[ L^i = g^{jk}u^{i}_{,jk} - \alpha \frac{\partial^2 x^i} {\partial x^j \partial x^j}\]

By default, \(\alpha\) is zero, resulting in the generalised Laplacian.

Parameters

inarray	Contravariant vector \(u^i\)
outarray	Result of the operation
alpha	The constant \(\alpha\)
