Constructor Detail

UniformMesh

public UniformMesh(double origin,
                   double step,
                   int count)

Constructs an uniform mesh. The affine transform of the original mesh is applied in such a way to convert the first and the last mesh nodes to 0 and n-1 correspondingly (here n is a nodes number).

Parameters:

origin - a first mesh node

step - a distance between nodes

count - a number of mesh nodes

Method Detail

averageStep

public double averageStep()

Returns an average mesh step.

Overrides:

averageStep in class SimpleMesh

findCell

public void findCell(SimpleMeshWorkspace workspace,
                     double x)

Finds a mesh cell to which a point belongs. Writes the cell index and a position within the cell (a distance in new coordinates from the left cell bound) into workspace's attributes cellIndex and cellPoint.

Overrides:

findCell in class SimpleMesh

Parameters:

workspace - a mesh workspace

x - a point (in original coordinates) to search

get

public final double get(int i)

Returns a value of i-th mesh node in the original coordinate system.

Overrides:

get in class SimpleMesh

isUniform

public final boolean isUniform()

Returns a mesh uniformness tag.

Overrides:

isUniform in class SimpleMesh

distance

public final double distance(int i,
                             int j)

Returns a distance between i-th and j-th nodes of transformed mesh, e.g. the value t_i-t_j.

Overrides:

distance in class SimpleMesh

extendedMeshDistance

public final double extendedMeshDistance(int i,
                                         int j)

Returns a distance between i-th and j-th nodes of the extended mesh.

Overrides:

extendedMeshDistance in class SimpleMesh
