at a specific node, and returns the (cross product) area associated with
that normal.

computeRestNodeNormal(Vector3d nrm,
FemNode3d node)
Computes the shell element normal, with respect to rest coordinates, at a
specific node, and returns the (cross product) area associated with that
normal.
|
double |
computeRestVolumes()
Computes the rest volume associated with this element and stores the
result in the
myRestVolume field. |
double |
computeVolumes()
Computes the volume associated with this element and stores the result in
the
myVolume field. |
void |
connectToHierarchy(CompositeComponent hcomp)
Called by the system after this component, or an ancestor of this
component, is added to the component hierarchy (i.e., added as
a child of another CompositeComponent).

copy(int flags,
java.util.Map<ModelComponent,ModelComponent> copyMap)
Create a copy of this component.

createElement(FemNode3d[] nodes,
double thickness,
boolean membrane,
boolean flipped) |
void |
disconnectFromHierarchy(CompositeComponent hcomp)
Called by the system after this component, or an ancestor of this
component, is removed from the component hierarchy (i.e., removed as a
child of its parent).

getAllPropertyInfo()
Returns a list giving static information about all properties exported by
this object.

such as rest Jacobians and the base stiffness for co-rotated
stiffness.

public double computeVolumes()
FemElementmyVolume field.
The method should return the minimum Jacobian determinant ratio (det(J)/det(J0)) over all integration points. A negative value indicates that the element is "inverted" at one or more integration points.
computeVolumes in class FemElementpublic double computeRestVolumes()
FemElementmyRestVolume field.
The method should return the minimum Jacobian determinant (det(J0)) over all integration points. A negative value indicates that the element is "inverted" in its rest position at one or more integration points.

ModelComponentBase When this method is called, ModelComponent.getParent() will return the new
parent component; the system will have set this beforehand.

original parent component; the system will set this to null
after.

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.copy in interface CopyableComponentcopy in class FemElement3dBaseflags - flags to control the copyingcopyMap - map to possible existing instances of referenced
