Member Function Documentation
| size_t MbHexahedronTopologyExplicitIjk< layout >::getBeginNodeId | ( | ) | const [inline, virtual] |
Returns the first node id used by this topology. This topology uses only node index in the interval [beginNodeId,EndNodeId[. Thus the maximum node index used by the topology is getEndNodeId() - 1 and the number of nodes used by this topology is getEndNodeId() - getBeginNodeId(). This default implementation returns 0.
Reimplemented from MiHexahedronTopologyExplicitIjk.

| ) | const [inline, virtual] |
Returns 8 indices of a cell of this topology.
The cell is identified by three id i,j,k.
Implements MiHexahedronTopologyExplicitIjk.

| size_t MbHexahedronTopologyExplicitIjk< layout >::getEndNodeId | ( | ) | const [inline, virtual] |
Returns the max node id +1 used by this topology.
This topology used only node index in the interval [beginNodeId,EndNodeId[. Thus the maximum node index used by the topology is getEndNodeId() -1 and the number of nodes used by this topology is getEndNodeId()-getBeginNodeId().
Implements MiHexahedronTopologyExplicitIjk.
| size_t MbHexahedronTopologyExplicitIjk< layout >::getNumCells | ( | ) | const [inline] |
Returns the number of cells.
| size_t MbHexahedronTopologyExplicitIjk< layout >::getNumCellsI | ( | ) | const [inline, virtual] |
Returns the number of cells on the first logical axis.
Reimplemented from MbTopologyIjk< layout >.
| size_t MbHexahedronTopologyExplicitIjk< layout >::getNumCellsJ | ( | ) | const [inline, virtual] |
Returns the number of cells on the second logical axis.
Reimplemented from MbTopologyIjk< layout >.
| size_t MbHexahedronTopologyExplicitIjk< layout >::getNumCellsK | ( | ) | const [inline, virtual] |
Returns the number of cells on the third logical axis.
Reimplemented from MbTopologyIjk< layout >.
| virtual MiMeshIjk::StorageLayout MbHexahedronTopologyExplicitIjk< layout >::getStorageLayout | ( | ) | const [inline, virtual] |
Hint about cells organization in memory.
This information aims at optimizing the topology traversal for extractors. Returns the topology internal cells layout in memory as 6 enum values covering all possible cases.
For instance LAYOUT_KJI means that:
- the cell (i+1,j,k) is consecutive in memory to the cell (i,j,k) and,
- the row of cells (j+1,k) is consecutive in memory to the row of cells (j,k) and,
- the slice of cells (k+1) is consecutive in memory to the slice of cells (k)
The fastest way to go through the cells with LAYOUT_KJI should be to perform the following triple loop:
for each k with 0 <= k < numK
for each j with 0 <= j < numJ
for each i with 0 <= i < numI
topology.getCellNodeIndices(i,j,k,n0, ... ,n7);
The default implementation returns LAYOUT_UNKNOWN meaning that the cell storage organization is unknown, for instance when cells are computed on the fly. In that case, extractors perform the topology traversal in the way that minimizes the required memory for their algorithms.

| bool MbHexahedronTopologyExplicitIjk< layout >::isDead | ( | size_t | i, | |
| size_t | j, | |||
| size_t | k | |||
| ) | const [inline, virtual] |
Returns true if the cell of index (i,j,k) should be ignored.
This value is ignored if the hasDeadCell() method returns false. The default implementation returns always false.
- Parameters:
-
(i,j,k) the index of the cell to check
