Vector At Point Class

Stores vectors at one domain point. Each vector corresponds to a "measurement" for which this vector was calculated.

Syntax

public class VectorAtPoint : ValueAtPointBase

Public Class VectorAtPoint
	Inherits ValueAtPointBase

public ref class VectorAtPoint : public ValueAtPointBase

type VectorAtPoint = 
    class
        inherit ValueAtPointBase
    end

The VectorAtPoint type exposes the following members.

Constructors

	Name	Description
	VectorAtPoint(IList XYZ )	Creates object from an array of vectors
	VectorAtPoint(VectorAtPoint)	Creates a copy of the given VectorAtPoint instance.

Example

C++

// Place analysis results in the form of vectors at each of a beam or column's analytical model curve
Transform transform = analyticalElem.GetTransform();
int index = spatialFieldManager.AddSpatialFieldPrimitive(curve, Transform.Identity);

IList<double> doubleList = new List<double>();
doubleList.Add(curve.GetEndParameter(0)); // vectors will be at each end of the analytical model curve
doubleList.Add(curve.GetEndParameter(1));
FieldDomainPointsByParameter pointsByParameter = new FieldDomainPointsByParameter(doubleList);

List<XYZ> xyzList = new List<XYZ>();
xyzList.Add(curve.ComputeDerivatives(0, true).BasisX.Normalize()); // vectors will be tangent to the curve at its ends
IList<VectorAtPoint> vectorList = new List<VectorAtPoint>();
vectorList.Add(new VectorAtPoint(xyzList));
xyzList.Clear();
xyzList.Add(curve.ComputeDerivatives(1, true).BasisX.Normalize().Negate());
vectorList.Add(new VectorAtPoint(xyzList));
FieldValues fieldValues = new FieldValues(vectorList);
