The core module

class nusa.core.Element(etype)

Bases: object

Superclass for all Elements

Attributes:

fx

fy

Methods

get_element_forces()	Returns a tuple with element forces: (fx, fy)
set_element_forces([fx, fy])	Set element forces
set_label(label)	Set the label property

get_nodes

property fx

property fy

get_element_forces()

Returns a tuple with element forces: (fx, fy)

get_nodes()

set_element_forces(fx=0.0, fy=0.0)

Set element forces

fxfloat

Force in x-dir

fyfloat

Force in y-dir

Normally this method is used by the solve method to update computed element-forces.

set_label(label)

Set the label property

labelint

Label, must be an integer

class nusa.core.Model(name, mtype)

Bases: object

Superclass for all Finite Element Analysis (FEA) models.

This class serves as a base container to manage nodes and elements, allowing derived models to build and manipulate FEA structures.

Methods

add_element(element)	Add an element to the model.
add_node(node)	Add a node to the model.
get_elements()	Return a list of element objects.
get_nodes()	Return a list of node objects.
get_number_of_elements()	Return the number of elements in the model.
get_number_of_nodes()	Return the number of nodes in the model.
simple_report([report_type, fname])	Placeholder for a future implementation of a simple report.

add_element(element)

Add an element to the model.

Parameters:

elementElement

Instance of an Element to be added.

Raises:

ValueError

If the element type does not match the model type.

add_node(node)

Add a node to the model.

Parameters:

nodeNode

Instance of a Node to be added.

Returns:

None

get_elements()

Return a list of element objects.

Returns:

list

List of Element instances.

get_nodes()

Return a list of node objects.

Returns:

list

List of Node instances.

get_number_of_elements()

Return the number of elements in the model.

Returns:

int

Total number of elements.

get_number_of_nodes()

Return the number of nodes in the model.

Returns:

int

Total number of nodes.

simple_report(report_type='print', fname='nusa_rpt.txt')

Placeholder for a future implementation of a simple report.

Parameters:

report_typestr, optional

Type of report to generate (‘print’, ‘file’, etc.).

fnamestr, optional

Output filename for file-based reports.

class nusa.core.Node(coordinates)

Bases: object
