Returns:

patch_list – List of patches corresponding to the surface

Return type:

list of matplotlib.patches.Polygon

rotate(angle)

Rotate the surface

Parameters:

None

translate(Zt)

Translate the Trapeze

Parameters:

  • Zt (complex) – Complex value for translation

Return type:

None

comp_point_ref(is_set=False)

Compute the point ref of the Surface

Parameters:

  • self (Trapeze) – A Trapeze object

  • is_set (bool) – True to update the point_ref property

Returns:

point_ref – the reference point of the surface

Return type:

complex

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
