Salome to CalculiX converter (unv to inp)

Converts Salome .unv file to CalculiX .inp format.

This converter is based on Joël's Cugnoni UNV parser available with CalculiX Launcher distribution. I allowed myself to slightely improve it and translate into Python 3. INPWriter's methods are fully refactored and now allow to convert beams. See folder examples for list of tested UNV elements. All generated INP files are processed by CalculiX GraphiX and CalculiX Adanced Environment without any errors.

Thanks to Niclas Stenberg for fixing bug with empty sets.

How to use

Download Linux and Windows binaries from the releases page. Binaries don't need to be installed.

Result INP-file name is the same as UNV-file name. So only one argument should be passed to the converter:

in Linux:       ./unv2ccx file.unv
in Windows:     unv2ccx.exe file.unv

For developers

To run this converter from source you'll need Python 3.

Install unv2ccx package with command:

pip3 install unv2ccx

In your code use unv2ccx package in this way:

import unv2ccx
c = unv2ccx.Converter(unv_file_name)
c.run()

If you have Python version >= 3.8 create binary with nuitka:

pip3 install nuitka

In Windows:
set CC=C:\\MinGW64\\mingw64\\bin\\gcc.exe
python3 -m nuitka --follow-imports --mingw64 __init__.py

In Linux:
python3 -m nuitka --follow-imports __init__.py

If you have Python version < 3.8 create binary with pyinstaller:

pip3 install pyinstaller
pyinstaller __init__.py --onefile

Read here about how to create packages for pypi.org:

python3 -m pip install --user --upgrade setuptools wheel twine
python3 setup.py sdist bdist_wheel
twine upload dist/*

TODO

• Multiprocessing for tests.
• Correctly convert UNV surface set into INP surface.
