Error thrown when attempting to retrieve the material of a Beam General Section.

static W800() → None

Warning raised when, given a list of elements, not all the elements have a composite PropertyType associated.

static W801() → None

Warning raised when trying to initialize a Property class with a wrong N2PProperty / N2PMaterial instance / user input

static W850(LC) → None

Warning raised when no Reference Temperature is set

static W851() → None

Warning raised when no

static user(message) → None

Method prepared to be used by the user so anyone who is using NaxToPy can write in the register their own warning message. Use the following structure as a standard message (W + four digits + Body).

“WXXXX: Body of the message”

classmethod activate_log() → None

Method that activates the .log

clv = 'WARNING'

classmethod deactivate_log() → None

Method that deactivates the .log

flv = 'INFO'

classmethod get_directory() → str

Method that returns the folder where the .log file is being saved

classmethod get_file_name() → str

Method that returns the name of the file of the .log

classmethod set_console_level(clv: Literal['DEBUG', 'INFO', 'WARNING', 'ERROR', 'CRITICAL']) → None

Method to set a different level for console register. The default level is “WARNING”. Only The level register and higher will be printed in the console. The possible levels are:

“DEBUG”, “INFO”, “WARNING”, “ERROR”, “CRITICAL”.

classmethod set_directory(value: str) → None

Method that sets the folder where the .log file must be saved

Parameters:

value – str -> Path to the folder where the .log must be saved.

classmethod set_file_level(flv: Literal['DEBUG', 'INFO', 'WARNING', 'ERROR', 'CRITICAL']) → None

Method to set a different level for the file .log of the register. The default level is “INFO”. Only The level register and higher will be printed in the .log file. Higher levels could make more difficult to track errors. The possible levels are:

“DEBUG”, “INFO”, “WARNING”, “ERROR”, “CRITICAL”.

classmethod set_file_name(value: str) → None

Method that sets the name of the file of the .log

Parameters:

value – str -> Name of the .log file

NaxToPy.envelope_list(*args: list) → list[list]

Function that generates the envelope of a cloud of points. Args could be DF or lists.

-args*: Lists as columns of the cloud of points: e = n2p.envelope([3,4,2,…], [6,2,7,…], …)

-arg: A single DataFrame: e = n2p.envelope(df)

Returns:

list[list]

Note

The column 0 is the solver element id when using DataFrame, but it is the position in the elements list when using lists!!! to know the solver id: get_elements()[index_0]

NaxToPy.envelope_ndarray(array2D: ndarray) → ndarray

Function that generates the envelope of a cloud of points. Args must be a numpy.array. This function is faster than envelope_list.

Parameters:

array2D (ndarray) – 2D Array [n*m]. Each row is point of the cloud, so there are n points. Each column is a coordinate of the point, so it is an m dimensional space.

Returns:

ndarray

Note

The column 0 is the position in the elements list!!! to know the solver id: get_elements()[index_0]

NaxToPy.initialize(path: str, parallelprocessing: bool = False) → N2PModelContent

Deprecated function. This funtion has been substituted by load_model()

NaxToPy.load_model(path: str, parallelprocessing: bool = True, file_type: Literal['InputFileNastran', 'InputFileAbaqus', 'Binary'] = None, dict_gen: dict = None, filter: Literal['ELEMENTS', 'PROPERTIES', 'PARTS', 'NODES'] = None) → N2PModelContent

Read an output result file in binary format from Nastran, Abaqus, Optistruct or Ansys and transform it into a N2PModelContent Object. It also can read models from input files in Nastran format.

Supports .op2, .xdb, .odb, .h5, .h3d and .rst file extensions read from a local filesystem or URL.

Supports Nastran Input Files (typically .bdf extension) and Abaqus Input File (typically .inp extension)

Parameters:

• path – str. Mandatory.

• parallelprocessing – bool. Optional. If true, the low libraries open the result files in several processes. It is slightly faster.

• file_type – str. Optional. It specifies if it is Nastran input file (“InputFileNastran”), Abaqus input file (“InputFileAbaqus”) or binary result file (“Binary”).

• filter – str. Optional. It specifies what to load in dict_gen (elements, properties, parts or nodes)

• dict_gem – dict. Optional. Dictionary that represents what elements/properties/parts/nodes to load. For elements and nodes, the dictionary is in the form {Part ID (str): [Elements ID/Nodes ID]}. For parts or properties, the dictionary could simply be in the form {Part ID (str) / Property ID (str): []}.

Returns:

Instance with all the model data.

Return type:

N2PModelContent

Examples

>>> model1 = load_model(r"C:\MODELS\FEM\model1.dat")

>>> # file_type is not needed. It only helps the program and saves a checking
>>> model2 = load_model(r"C:\MODELS\FEM\model2.dat", file_type="InputFileNastran")

>>> # parallelprocessing is only aviable for Binary files. It is helpful in some big files.
>>> model3 = load_model(r"C:\MODELS\RESULTS\model1.op2", parallelprocessing=True)

>>> model4 = load_model(r"C:\MODELS\RESULTS\model2.xdb", file_type="Binary")
>>> model5 = load_model(r"C:\MODELS\RESULTS\model5.h3d")
>>> model6 = load_model(r"C:\MODELS\RESULTS\model6.odb", True, "Binary")

NaxToPy.n2ptoexe(path: str, console: bool = True, solver: Literal['ALL', 'NASTRAN', 'ABAQUS', 'ANSYS', 'OPTISTRUCT'] = 'ALL', abaqusversion: list[Literal['2016', '2017', '2018', '2019', '2020', '2021', '2022', '2023', '2024', '6.11', '6.12', '6.13', '6.14']] = None, splash: str = '', extra_packages: list[str] = None, extra_files: list[str] = None, hidden_imports: list[str] = None) → None

Function that creates .exe files of programs that use NaxToPy

Parameters:

• path – str -> path of the module that will be used to create the .exe file

• console – bool -> If True (Default), the .exe will opne a console of python. If False, the .exe will not open any python console.

• solver – srt | list[str] -> Default=”ALL” Solver or list of solvers that the module will work with. Posible solvers are: “NASTRAN”, “ABAQUS”, “ANSYS”, “OPTISTRUCT”

• abaqusversion – str | list[srt] -> Default=’2022’. Only when “ABAQUS” is selected a str or a list of ABAQUS version are aviable. Posible abaqus versions: [‘2016’, ‘2017’, ‘2018’, ‘2019’, ‘2020’, ‘2021’, ‘2022’, ‘6.11’, ‘6.12’, ‘6.13’, ‘6.14’]

• splash – str -> Optional. Path to the splash image. If used, the user must introduce pyi_splash.close() at the beginning of the execution of the module. Import pyi_splash first. The splash image will appear during the .exe unpacking. Image should be png and smaller than 500x500 pixels.

• extra_packages – list[str] -> If some packages are not imported correctly by the function, they can be added manually. An example of a package that usually fails is ‘sv_ttk’.

• extra_files – list[str] -> Lis of path of extra dll, images or other files the user want to add the exe. The files will be saved in the ./bin directory inside the exe. To acces to the files use: path_file = os.path.join(sys._MEIPASS, r”binmylib.dll”)

Examples

>>> n2ptoexe(r"C:\Scripts\myscript1.py")
>>> n2ptoexe(r"C:\Scripts\myscript2.py", console=False, solver="NASTRAN")
>>> n2ptoexe(r"C:\Scripts\myscript3.py", console=True, solver="OPTISTRUCT", splash=r"C:\Scripts\mysplash.jpg")
>>> n2ptoexe(r"C:\Scripts\myscript4.py", extra_packages=["sv_ttk"], extra_files=[r"C:\Scripts\icon.png"])
>>> n2ptoexe(r"C:\Scripts\myscript5.py", hidden_imports=["plyer.platforms.win.notification"])
