ModelBH (class)

Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Material/ModelBH

class ModelBH(Bmax=2.31, Hmax=None, delta=100, init_dict=None, init_str=None)[source]

Bases: pyleecan.Classes._frozen.FrozenClass

Abstract class for BH curve model

VERSION = 1
get_BH()

Return the B(H) curve of the material (by default do nothing).

Parameters

self (ModelBH) – a ModelBH object

Returns

BH – B(H) values (two colums matrix: H and B(H))

Return type

numpy.ndarray

fit_model(BH)

Fit the BH model paramaters based on input B(H) curve of the material, and perform extrapolation.

Parameters
  • self (ModelBH) – a ModelBH object

  • BH (numpy.ndarray) – B(H) input values

  • Bmax (float) – Maximum B value required

  • Hmax (float) – Maximum H value required

Returns

new_BH – B(H) values (two colums matrix: H and B(H))

Return type

numpy.ndarray

save(save_path='', is_folder=False)

Save the object to the save_path

Parameters
  • self – A pyleecan object

  • save_path (str) – path to the folder to save the object

  • is_folder (bool) – to split the object in different files: separate simulation machine and materials

copy(**kwargs)

Return a copy of the class

get_logger()

Get the object logger or its parent’s one

Parameters

obj – A pyleecan object

Returns

logger – Pyleecan object dedicated logger

Return type

logging.Logger

compare(other, name='self')[source]

Compare two objects and return list of differences

as_dict(**kwargs)[source]

Convert this object in a json serializable dict (can be use in __init__). Optional keyword input parameter is for internal use only and may prevent json serializability.
