getDerivs()

static void getDerivs ( const MbVec3d &  ipcoord, std::vector< double > &  derivs  )

static

Gets the derivs of the point given by its iso parametric coordinates.

getIsoParametricCoord()

static MbVec3d getIsoParametricCoord ( size_t  nodeIndex )

static

Utility class for quadratic hexahedron cells with 21 nodes.

Utility class that provides a static implementation of the MiVolumeCell's methods for a quadratic hexahedron of 21 nodes. This class is provided to make easier the creation of a class that implements the MiVolumeCell interface for a quadratic hexahedron of 21 nodes.

• extraction of iso parametric coordinates in an hexahedron (see getIsoParametricCoord())
• extraction of the weights in a hexahedron (see getWeight())

ATTENTION: this class is not yet finished. When comparing with other MxXXXCellExtract, some methods are missing. Furthermore this class is not fully tested. Returns the iso parametric coordinates of the given node in the given cell (hexacell)

getSubTriangleNodesIndex()

static size_t getSubTriangleNodesIndex ( size_t  facet, std::vector< size_t > &  triangleNodeIds  )

static

Get a triangulation of a facet of this quadratic hexahedron.

Parameters

[in]	facet	number of the facet. (where: 0 <= face < getNumFacets() ).
[out]	triangleNodeIds	sub triangle node id (where: 0 <= triangleNodeIds[i] < getNumNodes() for each i).

Returns

the number of sub triangles in the facet of the is cell.

static void getWeight ( const MbVec3d &  ipcoord, std::vector< double > &  weights  )

static

getWeight() [2/2]

static void getWeight ( const MiGeometryI &  meshGeometry, const MiVolumeCell *  hexahedronCell, const MbVec3d &  point, std::vector< double > &  weights  )
