| class | ScdBox |
A structured mesh interface for MOAB-based data.
Structured mesh in MOAB is created and accessed through the ScdInterface and ScdBox classes.
Structured mesh can be constructed in one of two ways. First, a rectangular block of mesh, both vertices and edges/quads/hexes, can be created in one shot, using the construct_box method. In this case, there are single sequences of vertices/entities. The second method for creating structured mesh is to create the structured blocks of vertices and elements separately. In this case, different blocks of elements can share blocks of vertices, and each block of elements has its own independent parametric space. The algorithms behind this representation are described in T. Tautges, "MOAB-SD: Integrated structured and unstructured mesh representation", Eng. w Comp, vol 20 no. 3.
Structured mesh is represented in MOAB down at the element sequence level, which is something applications don't see. In addition, when structured mesh is created, entity sets are also created and tagged with information about the parametric space. In particular, the BOX_DIMS tag is used to indicate the lower and upper corners in parametric space (this tag is integer size 6). Structured mesh blocks are also available through ScdBox class objects returned by ScdInterface. These class objects should be treated only as references to the structured mesh blocks; that is, the structured mesh referenced by these objects is not deleted when the ScdBox instance is destroyed. Functions for destroying the actual mesh are available on this class, though.
Structured mesh blocks are returned in the form of ScdBox class objects. Each ScdBox instance represents a rectangular block of vertices and possibly elements (edges, quads, or hexes). The edge/quad/hex entity handles for a ScdBox are guaranteed to be contiguous, starting at a starting value which is also available through the ScdBox class. However, vertex handles may or may not be contiguous, depending on the construction method. The start vertex handle is also available from the ScdBox class.
Each structured box has a parametric (ijk) space, which can be queried through the ScdBox interface. For non-periodic boxes, the edge/quad/hex parameter bounds are one less in each dimension than that of the vertices, otherwise they are the same as the vertex parameter bounds. In a parallel representation, boxes are locally non-periodic by default, but global ids are assigned such that the last set of vertices in a periodic direction match those of the first set of vertices in that direction.
Entity handles are allocated with the i parameter varying fastest, then j, then k.
Boxes can be periodic in i, or j, or both i and j. If only i or j is periodic, the corresponding mesh is a strip or an annular cylinder; if both i and j are periodic, the corresponding mesh is an annular torus. A box cannot be periodic in all three parameters. If i and/or j is periodic, and assuming IMIN/JMIN is zero, the parameter extents in the/each periodic direction (IMAX/JMAX) for vertices and edges/faces/hexes are the same, and the vertices on the "top" end in the periodic direction are at parameter value IMIN/JMIN.
For parallel structured meshes, each local mesh (the mesh on a given process) looks like a non-periodic structured mesh, and there are both local and global parameters of the structured mesh. If the mesh is periodic in a given direction, the last process in the periodic direction has local IMAX/JMAX that is one greater than the global IMAX/JMAX.
In parallel, the periodicity described in the previous paragraph is "local periodicity"; there is also the notion of global periodicity. For serial meshes, those concepts are the same. In parallel, a mesh can be locally non-periodic but globally periodic in a given direction. In that case, the local mesh is still non-periodic, i.e. the parametric extents for edges is one fewer than that of vertices in that direction. However, vertices are given global ids such that they match those of the parametric minimum in that direction. Geometric positions of the vertices at the high end should still be greater than the ones just below.
This interface supports parametric access to intermediate-dimension entities, e.g. adjacent faces and edges in a 3d mesh. In this case, a direction parameter is added, to identify the parametric direction of the entities being requested. For example, to retrieve the faces adjacent to a hex with parameters ijk, in the i parametric direction, you would use the parameters ijk0. These intermediate entities are not stored in a structured representation, but their parametric positions can be evaluated based on their adjacencies to higher-dimensional entities. Thanks to Milad Fatenejad for the thinking behind this.
The ScdBox class provides functions for evaluating the mesh based on the ijk parameter space. These functions are inlined where possible, for efficiency.

Construct new structured mesh box, including both vertices and elements.
Parameter range for vertex box is [low-high], for elements is [low-high). Construct quads by passing in low[2] == high[2], and edges by passing in low[1] == high[1] and low[2] == high[2]. The result is passed back in a ScdBox*, which is a *reference* to the box of structured mesh. That is, the actual mesh is retained in MOAB when the ScdBox is destroyed. To actually destroy the mesh, call the destroy_mesh function on the ScdBox object first, before destroying it.
