VERSION
= 1¶
-
get_BH
()¶ Return the B(H) curve of the material according to the Import object. If there is no B(H) curve linear data are computed from mur_lin.
- Parameters
self (MatMagnetics) – a MatMagnetics object
- Returns
BH – B(H) values (two colums matrix: H and B(H))
- Return type
numpy.ndarray
-
plot_BH
(fig=None, grid=True)¶ Plot the curve B(H) at the specified frequency
- Parameters
self (MatMagnetics) – a MatMagnetics object
fig – if None, open a new fig and plot, else add to the gcf (Default value = None)
- Returns
- Return type
None
-
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
()¶ 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
