The ModelElement type exposes the following members.

Constructors

	Name	Description
	ModelElement	Initializes a new instance of the ModelElement class. parameterless constructor for json serialization.
	ModelElement(SerializationInfo, StreamingContext)	Initializes a new instance of the ModelElement class. Deserialize ModelElement.
	ModelElement(Int32, BuilderElement, IReadOnlyListInt32)	Initializes a new instance of the ModelElement class. construct model-element from a grass-element and use additional data provided.

Properties

	Name	Description
	builder_element	Gets the raw element from where the base data comes.
	canBuckle	Gets a value indicating whether buckling is considered when doing cross section optimization or calculating the utilization.
	color	Gets or sets the color of the element for some types of rendering. Can be set with a ElemSets-component.
	colorIsSet	Gets a value indicating whether the element has a color attached.
	crosec	Gets or sets the cross section of the model element.
	ecce	Gets the elements eccentricity.
	ecce_glo	Gets the vector of global cross section eccentricity.
	ecce_loc	Gets the vector of local cross section eccentricity.
	Elem_loads	Gets the elements loads.
	fe_id	Gets the first element index in fe-model. In case of shells there may be more than one finite element connected to a model element and fe_id points to the shells TriMesh-object.
	fe_ind_begin	Gets the first element index in fe-model. in case of shells there may be more than one finite element connected to a model element.
	fe_ind_end	Gets the index of element in femodel that lies one entry beyond the last finite element of the model element.
	fe_node_ind	Gets the index of fe-nodes of fe-elements in fe-model. Can differ from node_ind in case of joints.
	hasEccent	Gets a value indicating whether a cross section has an eccentricity.
	id	Gets the identifier (name) of element.
	ind	Gets the zero-based index of element in model. The indexes are consecutively numbered from 0 to number of elements.
	is_visible	Gets or sets a value indicating whether the element is visible.
	IsActive	Gets or sets a value indicating whether the element is active. If inactive the element is removed from the statical model using the soft-kill approach. The FE-model needs to be rebuilt after manipulating this flag.
	nII	Gets or sets the normal force that induces ThII effects.
	node_inds	Gets the index of nodes of elements after assembly.
	x_ori	Gets the user defined local x-axis of the element (not including the additional rotation angle alpha).
	x_ori_given	Gets a value indicating whether a user defined local x-axis is given.
	x_ori_list	Gets the user defined local x-axes of the element (not including the additional rotation angle alpha).
	y_ori	Gets the user defined local y-axis of the element (not including the additional rotation angle alpha).
	y_ori_given	Gets a value indicating whether a user defined local z-axis is given.
	z_ori	Gets the user defined local z-axis of the element (not including the additional rotation angle alpha).
	z_ori_given	Gets a value indicating whether a user defined local z-axis is given.
	z_ori_list	Gets the user defined local z-axes of the element (not including the additional rotation angle alpha).

Methods

	Name	Description
	Accept(ModelElementVisitor)	accept an element visitor.
	AcceptT(IModelElementVisitorT, T)	accept an element visitor.
	AcceptR, T(IModelElementVisitorR, T, T)	accept an element visitor.
	add	add an element load to the element.
	addLoads	add loads connected to this element to its feb-element.
	addStrainMesh	enrich the given mesh with strain data of this element.
	addStressMesh	enrich the given mesh with stress data of this element.
	addTo	create feb-element and add it to the feb-model.
	addUtilizationMesh	enrich the given mesh with utilization data of this element.
	build	Build elements (Beam, Truss, spring,..) out of grass-elements and additional information.
	BuilderElement	Clone the grass-element on which this model-element is based and linked to.
	characteristic_length	calculate characteristic length of the element.
	clearLoads	clears the loads of the element. Make sure to clone it before clearing the loads in order to avoid side effects.
	Clone	Clone the model element.
	cloneBuilderElement	Clone the grass-element on which this model-element is based and linked to.
	clonedBuilderElement	return the cloned grass-element on which this model-element is based or null.
	cog	calculate the center of gravity of the element.
	copyFEModelNodeIndexes	update the elements node indexes with those of the underlying finite element. This is necessary when topology of the feb-model changed.
	deformationEnergy	calculates axial deformation- and bending energy stored in the element.
	drawCroSecForceOutput	add lines of cross section forces diagrams to curves or meshes.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetCrossSectionsStates_OLD	Determines the states in predefined discrete points of the element.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetObjectData	Serialize ModelElement.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	is_inside	checks whether an Element lies partly inside a given Brep.
	localCoSys(Element)	create local coo-sys of undeformed element.
	localCoSys(PointState)	create local coo-sys of deformed element.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	midpoint_disp	return mid-point of deformed element.
	minmaxEpsX	determine extreme axial strains in model for the currently visible loadcase. Add result of element if necessary.
