Class PnVertexRKIgnoreDirection

java.lang.Object

jv.object.PsObject

jvx.numeric.PnGeodesicRK

jvx.numeric.PnVertexRKIgnoreDirection

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, PsUpdateIf

public class PnVertexRKIgnoreDirection
extends PnGeodesicRK

Discrete Runge-Kutta method on element sets. Vector field is given at vertices. Element set must be triangulated. Field is considered to be non-directed, so in each point we have two vectors (v2=-v1) to choose from.

Since:

JavaView 2.48.007

Constructor Detail

PnVertexRKIgnoreDirection

public PnVertexRKIgnoreDirection(PgElementSet geom)

Parameters:

geom - underlying triangulation

Method Detail

setVectorField

public void setVectorField(PdBaryDir[][] vec)

Set intrinsic vector field given at vertices.

Parameters:

vec - [elementindex][localvertexindex]

setVectorField

public void setVectorField(PgVectorField vec)

Set intrinsic vector field as projection of extrinsic vector field given at vertices. In each element choose +/- the original vectors: Look at one vertex and switch the others in same triangle such that they have least scalar product.

Parameters:

vec - vector field in adjacent space

eval

public void eval(int elemInd,
                 PdBary bary,
                 PdBaryDir out)

Returns +/- barycentric interpolation between vectors at vertices. The one with greater scalar product with parameter out is chosen. If out is zero, then the internal original is chosen.

Specified by:

eval in class PnGeodesicRK

Parameters:

elemInd - element in which the vector field will be evaluated

bary - barycentric coordinates of the point in which the vector field will be evaluated

out - output: in this PdBaryDir the evaluated direction will be stored
