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

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[source]#

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[source]#

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[source]#

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)

Args:

path: str 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:

model: 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[source]#

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"])
