Base class for cellshape matchers (hexMatch, prismMatch, etc.). These are classes which given a mesh and cell number find out the orientation of the cellShape and construct cell-vertex to mesh-vertex mapping and cell-face to mesh-face mapping.
For example,
hexMatcher hex(mesh); cellShape shape; .. bool isHex = hex.match(celli, shape);
Now shape is set to the correct Hex cellShape (if isHex is true)
Alternatively there is direct access to the vertex and face mapping:
const labelList& hexVertLabels = hex.vertLabels(); const labelList& hexFaceLabels = hex.faceLabels();
Now
hexVertLabels
[n] is vertex label of hex vertex nhexFaceLabels
[n] is face label of hex vertex nProcess of cellShape recognition consists of following steps:
The whole calculation is done such that no lists are allocated during cell checking. E.g. localFaces_ are always sized to hold max. number of possible face vertices and a separate list is filled which holds the actusl face sizes.
For now all hex-degenerates implemented. Numbering taken from picture in demoGuide.
