public interface MiCell
A cell is a basic volume, surface or edge element that connects adjacent nodes of a mesh. The MiCell interface is necessary to define the topology of unstructured 1D, 2D or 3D meshes.
MiCell
is the base interface that defines topological
characteristics of a cell (characteristics not depending on the cell
dimension):

Modifier and Type  Method and Description 

double[] 
getCenter(MiGeometryI geometry)
Gets the center of this cell.

long 
getNodeIndex(int node)
Gets the index (in the mesh) of a node.

int 
getNumNodes()
Gets the number of nodes.

double 
getRelativeSize(MiGeometryI meshGeometry)
Gets the relative size of the cell.

boolean 
isPointInsideCell(MiGeometryI meshGeometry,
double[] point,
double[] weights)
Checks if a point is inside or outside this cell.

If the point is inside this cell, the specified array is filled with weight values of the point. A weight value (aka shape function) must be given for each node of the cell, see chapter "Properties of shape functions" in the User's Guide for more details.
This method is not used by all extraction classes but it is needed for streamline extraction for example.
Note: For extraction purpose only, it is not necessary to allocate
the weight array since extraction classes are optimized such as weight
arrays passed to this method are already allocated and large enough to
retrieve all the computed weights. Thus the following assignment is then
sufficient: weight[i] = wi
for each i with 0 <= i < getNumNodes

coordinatesdouble getRelativeSize(MiGeometryI meshGeometry)
This method is used only by the
MoMeshCellShape
to
display node names if using the relative offset feature and the streamline
extraction to adapt the step integration to the size of the cell.
getRelativeSize
should return a value depending on the size of
the cell. For instance, getRelativeSize
can return the length
of the longest edge of this cell, or the length of its diagonal.
If getRelativeSize
returns a constant value for any cell, the
stream line extraction uses a constant number of step integration anywhere
in the mesh. Returning a constant implies that all the cells are supposed
to have the same size. getRelativeSize
) must not return 0.
