XOutput (class)

Method code available at https://github.com/Eomys/pyleecan/tree/master/pyleecan/Methods/Output/XOutput

class XOutput(paramexplorer_list=-1, output_list=-1, xoutput_dict=-1, nb_simu=0, simu=-1, path_result='', geo=-1, elec=-1, mag=-1, struct=-1, post=-1, logger_name='Pyleecan.Output', force=-1, init_dict=None, init_str=None)[source]

Bases: pyleecan.Classes.Output.Output

XOutput object: gather all the outputs of all the modules for multiple simulations

VERSION = 1
count(x)

Return the number of times x appears in the list.

insert(i, x)

Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a), x) is equivalent to a.append(x).

pop(i)

Remove the item at the given position in the list, and return it. If no index is specified, a.pop() removes and returns the last item in the list.

remove(x)

Remove the first item from the list whose value is equal to x. It raises a ValueError if there is no such item.

append(elem)

Method to behave like a list and access quickly to output_list

get_simu(index)

Generate a simulation according to index

Parameters

index (int) – simulation index

Returns

simu – simulation generated

Return type

Simulation

keys()

Return xoutput_dict keys to behave like a dict

items()

Returns self.xoutput_dict.items to behave like a dict

get_param_simu(idx)

Return the list of parameter values for a specific simulation

get_paramexplorer(symbol)

Get the ParamExplorer with symbol :param symbol: ParamExplorer symbol :type symbol: str

plot_multi(x_symbol, y_symbol, plot_type='scatter', idx=None, ax=None, title=None)

Plot data from a DataKeeper for a given parameter from a ParamExplorer

x_symbol: str

ParamExplorer or DataKeeper symbol

y_symbol: str

ParamExplorer or DataKeeper symbol

plot_type: str

scatter or plot to chose plot type

idx: slice

To plot only some data

ax: matplotlib.pyplot.Axe

To put the plot in a specific ax

title: str

Figure or subfigure title according to ax

Returns

Return type

fig or ax

Raises

PlotError

plot_pareto(x_symbol, y_symbol, c_symbol=None, cmap=None, ax=None, title=None, grid=False)

Plot the pareto front for 2 objective functions

Parameters
  • self (XOutput) –

  • x_symbol (str) – symbol of the first objective function

  • y_symbol (str) – symbol of the second objective function

  • c_symbol (str) – optional symbol to set the plot colors

  • cmap (colormap) – optional colormap

plot_generation(x_symbol, y_symbol, ax=None)

Plot every fitness values according to the two fitness

Parameters
  • self (XOutput) –

  • obj1 (str) – symbol of the ParamExplorer or the DataKeeper

  • obj2 (str) – symbol of the ParamExplorer or the DataKeeper

get_pareto_index()

Return index of individuals in the pareto

Parameters

self (XOutput) –

Returns

idx_non_dom – list of index of non dominated individuals

Return type

list

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
