SyntaxThe ModelElement type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | ModelElement |
construct model-element from a grass-element and use additional data provided
|
Properties| Name | Description | |
|---|---|---|
 | builder_element | raw element from where the base data comes |
 | canBuckle |
if true buckling is considered when doing cross section optimization or calculating
the utilization
|
| color |
color of the element for some types of rendering. Can be set with a ElemSets-component
|
| colorIsSet |
return true if the element has a color attached
|
| crosec |
set/get cross section of the model element
|
| ecce |
return the elements eccentricity
|
| ecce_glo |
return vector of global cross section eccentricity
|
| ecce_loc |
return vector of local cross section eccentricity
|
| Elem_loads | the elements loads |
| fe_id |
get 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 |
get 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 |
get index of element in femodel that lies one entry beyond the last finite element of the model element.
|
| fe_node_ind | index of fe-nodes of fe-elements in fe-model. Can differ from node_ind in case of joints |
| hasEccent |
return true if cross section has an eccentricity
|
| id |
return identifier (name) of element
|
| ind |
zero-based index of element in model.
The indexes are consecutively numbered from 0 to number of elements.
|
| is_active |
set/get activation state of the element. 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.
|
| is_visible |
return true if element is visible
|
| nII |
set get normal force that induces ThII effects
|
| node_inds | index of nodes of elements after assembly |
| x_ori |
get the user defined local x-axis of the element
(not including the additional rotation angle alpha)
|
| x_ori_given |
return true if a user defined local x-axis is given
|
| x_ori_list |
get the user defined local x-axes of the element
(not including the additional rotation angle alpha)
|
| y_ori |
get the user defined local y-axis of the element
(not including the additional rotation angle alpha)
|
| y_ori_given |
return true if a user defined local z-axis is given
|
| z_ori |
get the user defined local z-axis of the element
(not including the additional rotation angle alpha)
|
| z_ori_given |
return true if a user defined local z-axis is given
|
| z_ori_list |
get 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(ModelElementVisitorT, T) |
accept an element visitor
|
| AcceptR, T(ModelElementVisitorR, 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 |
builds elements (Beam, Truss, spring,..) out of grass-elements and additional information.
|
| 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.) |
| getElementStates |
determines the states in discrete points of the element
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| 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
|
| maxCroSecForceOutput |
returns the resultant value of the largest cross section force output.
Can e.g. be used to scale graphical output.
|
| 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.
|
| referencePointOnZAxis |
return reference point on local z-axis for local coordinate system being
situated at first element node.
|
| resultantCroSecForces |
calculates resultant normal force (N), shear force (V) and moment (M) in an element
|
| scaledState |
return scaled state at given element, location; superimpose loadcases if lc_num is smaller than 0;
unscaled loadcase for lc_num % model.numLC if lc_num >= model.numLC (is used for retrieval of beam results)
|
| set_fe_and_model_index |
set the element and fe_element index
|
| set_is_active |
set activation state of element and synchronize it with fe-model. An extra fe-model-generation
step is not necessary. Is therefore fast.
|
| SetNodeInds |
set the node indexes of the element
|
| snapElement |
change the element if nodes snap together according to the given list of
node indexes.
returns true if the element was completely snapped
|
| split_elem |
The element with index ind is the seed of an element split. Make all splits
in the model that are necessary so that feb-model and model are synchronized.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| totalEccentricity |
returns the eccentricity of the element in global coordinates
|
| weight |
return weight of the element in kN
|
