Module Contents

anastruct.fem.system_components.assembly.set_force_vector(system: anastruct.fem.system.SystemElements, force_list: List[Tuple[int, anastruct._types.AxisNumber, float]]) → numpy.ndarray

Set a force vector on a node within the system

Args:

system (SystemElements): System to which the force vector is applied force_list (List[Tuple[int, AxisNumber, float]]): List of tuples containing

the node id, direction (1 = x, 2 = y, 3 = z), and force magnitude

Returns:

np.ndarray: System force vector with the applied forces on the nodes

anastruct.fem.system_components.assembly.prep_matrix_forces(system: anastruct.fem.system.SystemElements) → None

Prepare the system force vector for the matrix assembly

Args:

system (SystemElements): System to which the force vector is applied

anastruct.fem.system_components.assembly.apply_moment_load(system: anastruct.fem.system.SystemElements) → None

Apply a moment load to the system

Args:

system (SystemElements): System to which the moment load is applied

anastruct.fem.system_components.assembly.apply_point_load(system: anastruct.fem.system.SystemElements) → None

Apply a point load to the system

Args:

system (SystemElements): System to which the point load is applied

anastruct.fem.system_components.assembly.apply_perpendicular_q_load(system: anastruct.fem.system.SystemElements) → None

Apply a perpendicular q load to the system

Args:

system (SystemElements): System to which the perpendicular q load is applied

anastruct.fem.system_components.assembly.apply_parallel_qn_load(system: anastruct.fem.system.SystemElements) → None

Apply a parallel qn load to the system

Args:

system (SystemElements): System to which the parallel qn load is applied

anastruct.fem.system_components.assembly.dead_load(system: anastruct.fem.system.SystemElements, g: float, element_id: int) → None

Apply a dead load self-weight to an element in the system

Args:

system (SystemElements): System to which the dead load is applied g (float): Magnitude of the dead load self-weight element_id (int): Element id to which the dead load is applied

anastruct.fem.system_components.assembly.assemble_system_matrix(system: anastruct.fem.system.SystemElements, validate: bool = False, geometric_matrix: bool = False) → None

Assemble the system matrix Shape of the matrix = n nodes * n d.o.f. = n * 3

Args:

system (SystemElements): System to be prepared validate (bool, optional): Whether or not to validate the system. Defaults to False. geometric_matrix (bool, optional): Whether or not to include the current geometric matrix. Defaults to False.

anastruct.fem.system_components.assembly.set_displacement_vector(system: anastruct.fem.system.SystemElements, nodes_list: List[Tuple[int, anastruct._types.AxisNumber]]) → numpy.ndarray

Set the displacement vector for the system

Args:

system (SystemElements): System to which the displacement vector is applied nodes_list (List[Tuple[int, AxisNumber]]): List of tuples containing

the node id and the direction (1 = x, 2 = y, 3 = z)

Raises:

IndexError: This often occurs if you set supports before the all the elements are

modelled. First finish the model.
