Detailed Description

Defines expert-level interfaces for the evaluation of functions and operators in physical space (supported for FE, FV, and FD methods) and FE reference space; in addition, provides several function transformation utilities.

The functionality here largely mirrors that in Intrepid::FunctionSpaceTools, except that the input data is overwrriten with the result of the particular transformation. This can reduce intermediate storage when the input values are not required by later calculations.

A new feature compared to Intrepid::FunctionSpaceTools is that of "dual" transforms that are useful in alternate workflow patterns. At the innermost loop nest, we may have a computation of the form (T_1 D_1 u).(T_2 D_2 v), and we would like to rewrite this as (T_2^t T_1 D_1 u).(D_2 v). The transposes of each of these transformations are supplied in this routine.

const ArrayTypeJac &  jacobian,
const ArrayTypeDet &  jacobianDet,
const char  transpose = 'N' 
)
static

Transformation of a curl field in the H-curl space, defined at points on a reference cell, stored in the user-provided container inVals and indexed by (F,P,D), into the output container outVals, defined on cells in physical space and indexed by (C,F,P,D). 

     Computes pullback of curls of \e HCURL functions

$\Phi^*(\widehat{\bf u}_f) = \left(J^{-1}_{c} DF_{c}\cdot\nabla\times\widehat{\bf u}_f\right)\circ F^{-1}_{c}$ for points in one or more physical cells that are images of a given set of points in the reference cell:

\[ \{ x_{c,p} \}_{p=0}^P = \{ F_{c} (\widehat{x}_p) \}_{p=0}^{P}\qquad 0\le c < C \,. \]

In this case $ F^{-1}_{c}(x_{c,p}) = \widehat{x}_p $ and the user-provided container should contain the curls of the vector function set $\{\widehat{\bf u}_f\}_{f=0}^{F}$ at the reference points:

\[ inVals(f,p,*) = \nabla\times\widehat{\bf u}_f(\widehat{x}_p) \,. \]

The method returns

\[ outVals(c,f,p,*) = \left(J^{-1}_{c} DF_{c}\cdot\nabla\times\widehat{\bf u}_f\right)\circ F^{-1}_{c}(x_{c,p}) = J^{-1}_{c}(\widehat{x}_p) DF_{c}(\widehat{x}_p)\cdot\nabla\times\widehat{\bf u}_f(\widehat{x}_p) \qquad 0\le c < C \,. \]
