Methods to support a custom interpolation procedure.
The physical-space point that the user seeks to interpolate at could be located inside an element on another mpi rank. To enable a custom interpolation procedure (e.g., strain tensor computation) we need a mechanism to first send element indices and reference-space coordinates to the mpi-ranks where each point is found. Then the custom interpolation can be done locally by the user before sending the interpolated values back to the mpi-ranks that the query originated from. Example usage looks something like this: FindPoints() -> DistributePointInfoToOwningMPIRanks() -> Computation by user -> DistributeInterpolatedValues().

Detailed Description

FindPointsGSLIB can robustly evaluate a GridFunction on an arbitrary collection of points. See Mittal et al., "General Field Evaluation in High-Order Meshes on GPUs". (2025). Computers & Fluids. for technical details.

There are three key functions in FindPointsGSLIB:

Setup - constructs the internal data structures of gslib. See Setup.
FindPoints - for any given arbitrary set of points in physical space, gslib finds the element number, MPI rank, and the reference space coordinates inside the element that each point is located in. gslib also returns a code that indicates whether the point was found inside an element, on element border, or not found in the domain. For points returned as found on element border, the point is either on an element edge/face or near the domain boundary, and gslib also returns a distance to the border. Points near (but outside) the domain boundary must then be marked as not found using the distance returned by gslib. See FindPoints.
Interpolate - Interpolates any grid function at the points found using 2. For functions in L2 finite element space, use SetL2AvgType to specify how to interpolate values at points located at element boundaries where the function might be multi-valued. See Interpolate.

FindPointsGSLIB also provides interface to use these functions through a single call.

For custom interpolation (e.g., evaluating strain rate tensor), we provide functions that use gslib to send element index and corresponding reference-space coordinates for each point to the mpi rank that the element is located on. Then, custom interpolation can be defined locally by the user before sending the values back to mpi ranks where the query originated from. See DistributePointInfoToOwningMPIRanks and DistributeInterpolatedValues.

Return the oriented bounding boxes (OBB) computed during Setup. Each OBB is represented using the inverse transformation (A^{-1}) and its center (x_c), such that a point x is inside the OBB if: -1 <= A^{-1}(x-x_c) <= 1. The inverse transformation is returned in obbA, a DenseTensor of size (dim x dim x nel), and the OBB centers are returned in obbC, a vector of size (nel x dim). The vertices of the OBBs are returned in obbV, a vector of size (nel x nverts x dim) .

◆ SetupSurfBase()

void mfem::FindPointsGSLIB::SetupSurfBase	(	Mesh &	m,
		const double	bbox_rel_size_inc,
		const Vector *	aabb_sz_inc,
		const double	newt_tol )

protected

Shared implementation for the public surface-setup methods.

Initializes the surface-search data structures, builds the split-element representation expected by gslib, and constructs the element bounding boxes used by the MFEM surface kernels.

If aabb_sz_inc is null, the setup stores the default oriented bounding boxes and uses bbox_rel_size_inc as their relative size increase factor.

If aabb_sz_inc is non-null, the setup stores axis-aligned bounding boxes only, applies the requested absolute AABB expansion in each physical direction, and adjusts the tolerance bdr_tol so points found in the expanded region are classified as border points.

Parameters

[in]	m	Input surface mesh.
[in]	bbox_rel_size_inc	Relative size increase applied when expanding each element bounding box during setup.
[in]	aabb_sz_inc	Optional total absolute AABB expansion applied to the stored axis-aligned bounding boxes after construction.
[in]	newt_tol	Newton tolerance for the point-search kernels.

Definition at line 1207 of file gslib.cpp.

◆ SetupSurfWithAABBExpansion()

void mfem::FindPointsGSLIB::SetupSurfWithAABBExpansion	(	Mesh &	m,
		const Vector &	aabb_sz_inc,
		const double	newt_tol = 1.0e-12 )

Preprocess the surface mesh to compute data for FindPoints using absolute AABB expansion.

This method computes only axis-aligned bounding boxes and increases their total length by a user-specified amount in each physical direction. The absolute AABB expansion is applied symmetrically to the lower and upper bounds.

The size of aabb_sz_inc determines how the expansion values are interpreted:

1: one expansion value used in every direction for every element
NElements: one expansion value per element, reused in x/y/z directions
SpaceDim: one expansion value per physical direction, reused for every element
NElements*SpaceDim: one expansion value per element and direction, ordered as (dx1,dy1,dz1, ... dxN,dyN,dzN)

This method disables the oriented bounding-box precheck because the stored boxes are modified only in their axis-aligned representation.

Parameters

[in]	m	Input surface mesh.
[in]	aabb_sz_inc	Total absolute AABB expansion applied in each physical direction to the stored axis-aligned bounding boxes.
[in]	newt_tol	Newton tolerance for the point-search kernels.

Note: We disable the oriented bounding box check with this setup. bdr_tol is also adjusted so that all points in the AABBs can be found.
