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
inarrayContravariant vector $u^i$
outarrayResult of the operation
alphaThe constant $\alpha$
