FemNode

Method Detail

getMass

public double getMass()

Overrides:

getMass in class Particle

setMass

public void setMass(double m)

Overrides:

setMass in class Particle

addMass

public void addMass(double m)

scaleMass

public void scaleMass(double s)

Description copied from interface: ScalableUnits

Scales all mass units.

Specified by:

scaleMass in interface ScalableUnits

Overrides:

scaleMass in class Particle

Parameters:

s - scaling factor

clearMass

public void clearMass()

setExplicitMass

public void setExplicitMass(double mass)

Sets the mass for this node to an explicit value. This means that the mass will no longer be determined from the masses of the surrounding elements.

Parameters:

mass - explicit mass value

unsetExplicitMass

public void unsetExplicitMass()

Unsets an explicit mass for this node. This means that the mass will be determined from the masses of the surrounding elements.

isMassExplicit

public boolean isMassExplicit()

Queries whether the mass for this node has been explicitly set.

Returns:

true if the mass has been explicitly set

invalidateMassIfNecessary

public void invalidateMassIfNecessary()

computeMassFromDensity

public abstract double computeMassFromDensity()

scanItem

public boolean scanItem(ReaderTokenizer rtok,
                        java.util.Deque<ScanToken> tokens)
                 throws java.io.IOException

Throws:

java.io.IOException

copy

public FemNode copy(int flags,
                    java.util.Map<ModelComponent,ModelComponent> copyMap)

Description copied from interface: CopyableComponent

Create a copy of this component. If COPY_REFERENCES is set in flags, then any component referenced by this component should itself be set to a copy. This should be done first checking copyMap for an existing copy of the referenced component. If there is no existing copy, then a copy should be created by calling copy recursively and adding the new copy to copyMap.

Specified by:

copy in interface CopyableComponent

Overrides:

copy in class Particle

Parameters:

flags - flags to control the copying

copyMap - map to possible existing instances of referenced components

Returns:

copy of this component

getRestPosition

public abstract Point3d getRestPosition()
