Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Simulation/OP

class OP(N0=None, felec=None, Tem_av_ref=None, Pem_av_ref=None, Pem_av_in=None, efficiency=None, init_dict=None, init_str=None)[source]

Bases: FrozenClass

Define the Operating Point of the simulation

VERSION = 1
get_machine_from_parent()

Search in the parent to find the machine

Parameters:

self (OP) – An OP object

Returns:

machine – Machine from the parent (or None)

Return type:

Machine

get_OP_array(*arg_list)

get the OP_matrix by identifying the columns Ex: get_OP_array(“N0”, “Iq”, “Iq”, “Tem”) get_OP_array(OP_matrix) calls get_OP_array(“N0”, “Id”, “Iq”, “Tem”, “Pem”)

Parameters:

  • self (OP) – Operating Point object to convert to a matrix

  • *arg_list (list of str) – arguments to specify the OP_matrix columns name

Returns:

OP_matrix – Single line OP_matrix with the selected columns

Return type:

ndarray

save(save_path='', is_folder=False, type_handle_old=2, type_compression=0)

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 (json only)

  • type_handle_old (int) – How to handle old file in folder mode (0:Nothing, 1:Delete, 2:Move to “Backup” folder)

  • type_compression (int) – Available only for json, 0: no compression, 1: gzip

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', ignore_list=None, is_add_value=False)[source]

Compare two objects and return list of differences

as_dict(type_handle_ndarray=0, keep_function=False, **kwargs)[source]

Convert this object in a json serializable dict (can be use in __init__). type_handle_ndarray: int

How to handle ndarray (0: tolist, 1: copy, 2: nothing)

keep_functionbool

True to keep the function object, else return str

Optional keyword input parameter is for internal use only and may prevent json serializability.

Creates a deepcopy of the object
