pyHarm.CoordinateSystem¶

Classes¶

`CoordinateSystem`	Class that represents a coordinate system. It allows for generating local coordinate systems
`GlobalCoordinateSystem`	Subclass of CoordinateSystem that allows defining global coordinate systems.

Functions¶

generateCoordinateSystem(dirs)

Generates a CoordinateSystem object based on the provided directions.

Module Contents¶

pyHarm.CoordinateSystem.generateCoordinateSystem(dirs: list[list[float]])¶

Generates a CoordinateSystem object based on the provided directions.

Parameters:: dirs (list[list[float]]) – A list of lists containing the directions relative to the global coordinate system.
Returns:: A CoordinateSystem object.
Return type:: CoordinateSystem

class pyHarm.CoordinateSystem.CoordinateSystem(dirs: list[list[float]])¶

Class that represents a coordinate system. It allows for generating local coordinate systems to be attached to elements or substructures and transfering their residuals and Jacobians to the global coordinate system.

Parameters:: dirs (list[list[float]]) – A list of lists containing the directions relative to the global coordinate system.

dirs¶

n_dirs¶

n_component¶

checkOrthonormal()¶

Checks if the provided coordinate system is orthonormal.

Raises:: ValueError – If the coordinate system is not orthonormal.

getTM(nh: int | list[int], component: list[int]) → numpy.ndarray¶

Generates a transform matrix of size (ncompo, ncompo, n_dirs).

Parameters:

nh (int) – Number of harmonics.
component (list[int]) – The components of the transform matrix.

Returns:

The generated transform matrix.

Return type:

np.ndarray

class pyHarm.CoordinateSystem.GlobalCoordinateSystem(ndirs: int)¶

Bases: CoordinateSystem

Subclass of CoordinateSystem that allows defining global coordinate systems. The initialization is modified for ease of instantiation.

Parameters:: ndirs (int) – The number of directions in the global coordinate system.

dirs¶

n_dirs¶

n_component¶
