Detailed Description

template<typename ExecSpace, int ORDER = 2>
class axom::quest::TriangleGWNQuery< ExecSpace, ORDER >

Preprocesses a triangle mesh for GWN evaluation, and performs the calculation on the DOFs of an input MFEM mesh.

Template Parameters

ExecSpace	The execution space for the algorithm.
ORDER	If agglomeration is used, this is the order of the Taylor expansion.

Possible evaluation modes are use_direct_eval : If true, evaluation is done triangle-by-triangle. If false, evaluation is sped up with agglomeration via Taylor-expansion

inline

Evaluate the GWN for a query grid at the DOFs of the dc query mesh.

Parameters

[in]	dc	A query grid to be evaluated at the DOFs
[in]	tol	A collection of possible tolerances for GWN evaluation
[in]	slice_z	If the dc mesh is 2D, the GWN will be evaluated on a slice parallel to the x-y plane with this offset on the z-axis
