public class Vector3dNodalField
extends VectorNodalField<Vector3d>

A vector field, for vectors of type Vector3d, defined over an FEM model, using values set at the nodes. Values at other points are obtained by nodal interpolation on the elements nearest to those points. Values at nodes for which no explicit value has been set are given by the field's default value.

Constructor Detail

Vector3dNodalField

public Vector3dNodalField()

This constructor should not be called by applications, unless ModelComponentBase.scan(maspack.util.ReaderTokenizer, java.lang.Object) is called immediately after.

Vector3dNodalField

public Vector3dNodalField(FemModel3d fem)

Constructs a field for a given FEM model, with a default value of 0.

Parameters:

fem - FEM model over which the field is defined

Vector3dNodalField

public Vector3dNodalField(FemModel3d fem,
                          Vector3d defaultValue)

Constructs a field for a given FEM model and default value.

Parameters:

fem - FEM model over which the field is defined

defaultValue - default value for nodes which don't have explicitly set values

Vector3dNodalField

public Vector3dNodalField(java.lang.String name,
                          FemModel3d fem)

Constructs a named field for a given FEM model, with a default value of 0.

Parameters:

name - name of the field

fem - FEM model over which the field is defined

Vector3dNodalField

public Vector3dNodalField(java.lang.String name,
                          FemModel3d fem,
                          Vector3d defaultValue)

Constructs a named field for a given FEM model and default value.

Parameters:

name - name of the field

fem - FEM model over which the field is defined

defaultValue - default value for nodes which don't have explicitly set values

Method Detail

hasParameterizedType

public boolean hasParameterizedType()

Queries whether this class explicitly utilizes a parameterized type. This methods allows ParameterizedType subclasses to not be explicitly parameterized.

Specified by:

hasParameterizedType in interface ParameterizedClass

Overrides:

hasParameterizedType in class VectorFemField<Vector3d>

Returns:

true if this class utilizes a parameterized type.

getValue

public Vector3d getValue(int[] nodeNums,
                         double[] weights)

Overrides:

getValue in class VectorNodalField<Vector3d>

setFromPolylines

public void setFromPolylines(PolylineMesh mesh,
                             double rad)

Sets the values for this field from a polyline mesh which specifies a direction field. For each node, the nearest mesh point is found and then used to compute the vector value by averaging directions within a given radius.

Parameters:

mesh - polyline mesh giving the direction field

rad - direction averaging radius
