Direct Known Subclasses:

PbCartesianGrid2D, PbPolarGrid2D, PbRegularCartesianGrid2D

public class PbGrid2D
extends PbMesh2D

Defines an abstract grid surface mesh. This class defines a mesh of which topology is a regular grid made of num_x * num_y nodes. Each node with index (i, j) in the mesh (except for points along the mesh border) is connected to four points with indices (i+1,j), (i,j+1), (i-1,j), (i,j-1).

The values on the mesh nodes are defined by the PbMesh.addValuesSet() method, where val argument is an array of num_x * num_y floats.

Method Detail

setGeometry

public void setGeometry(int num_x,
                        int num_y,
                        float[] x,
                        float[] y)

Defines a 2D surface mesh geometry. The size of the x array depends on the derived class that calls this method. It is either num_x or num_x * num_y. Idem for y array.

getNodeIndices

public int[] getNodeIndices(int nod_index)

Calculates indices i,j that verify nod_index = i*num_y + j.

getDim

public int[] getDim()

Gets the dimensions num_x, num_y of the grid.

getNodeCoord

public SbVec3f getNodeCoord(int i,
                            int j)

Gets the coordinates of a node defined by its i,j indices on the grid.

setGeometry

public void setGeometry(int num_x,
                        int num_y,
                        float[] x,
                        float[] y,
                        float[] z)

Defines a 3D surface mesh geometry. The size of the x array depends on the derived class that calls this method. It is either num_x or num_x * num_y. Idem for y array. The size of z array is always num_x * num_y.

getCellIndices

public int[] getCellIndices(int cell_index)

Calculates indices i,j that verify cell_index = i*(num_y-1) + j.
