void compute ( const Array< T_GRID, T > &  alpha,
Array< T_GRID, Vec3< T >> &  grad_alpha 
)

Compute gradient of scalar.

For a scalar the gradient is stored in Vec3, for e.x.: \(\left(\nabla \alpha\right)_i = \{\partial_x \alpha, \partial_y \alpha, \partial_z \alpha\}_i.\)

Parameters
alphascalar variable for which gradient will be computed.
grad_alphagradient of alpha is written to this.

void compute ( const Array< T_GRID, Vec3< T >> &  alpha,
Array< T_GRID, Mat3< T >> &  grad_alpha 
)

Compute gradient of Vec3.

For a Vec3 the gradient is stored in Mat3, for e.x.: Let \(\boldsymbol{u} = \{u, v, w\} \) then, \(\left(\nabla \boldsymbol{u}\right)_i = \begin{bmatrix}\partial_x u & \partial_y u & \partial_z u \\ \partial_x v & \partial_y v & \partial_z v \\ \partial_x w & \partial_y w & \partial_z w \end{bmatrix}_i.\)

Parameters
alphaVec3 variable for which gradient will be computed.
grad_alphagradient of alpha is written to this.

Definition at line 69 of file third-order.cc.

void operator() ( const Array< T_GRID, T > &  alpha,
Array< T_GRID, Vec3< T >> &  grad_alpha 
)

grad_alphagradient of alpha is written to this.
