GeneralDisplacement

class compas_fea2.problem.GeneralDisplacement

Bases: FEAData, Frameable

General imposed displacement.

Represents imposed displacements or restraints on degrees of freedom in a local coordinate frame. Supports translation and rotation components.

Parameters:

x, y, zbool, optional

Translational displacement restraints along local x, y, z axes.

xx, yy, zzbool, optional

Rotational displacement restraints about local x, y, z axes.

frameFrame or None, optional

Local coordinate frame for the displacement.

Notes

This class only handles boolean restraint flags and an optional local frame. There are no numeric magnitudes to unit-normalize here, so no units decorator is applied.

Methods

global_constraint_equations

Return linear constraint equations in global translational DOFs implied by local restraints.

Inherited Methods

ToString	Converts the instance to a string.
clear_frame	Clear the local frame, reverting to GLOBAL_FRAME.
copy	Make an independent copy of the data object.
direction_cosines	Return local axes expressed as global vectors (x, y, z).
from_json	Construct an object of this type from a JSON file.
from_jsonstring	Construct an object of this type from a JSON string.
is_axis_aligned	Return True if local frame coincides with GLOBAL frame within tolerance.
sha256	Compute a hash of the data for comparison during version control using the sha256 algorithm.
to_global_point	Convert a local point to the global frame.
to_global_vector	Convert a local vector to the global frame.
to_json	Convert an object to its native data representation and save it to a JSON file.
to_jsonstring	Convert an object to its native data representation and save it to a JSON string.
to_local_point	Convert a global point to the local frame.
to_local_vector	Convert a global vector to the local frame.
transform_to	Get the transformation from this object's local frame to another frame.
validate_data	Validate the data against the object's data schema.
