16、tandardized.If your organization is recently migrating to Abaqus/CAE, building a vertical application using Abaqus Scripting need not involve reinventing the wheel.One of Pythons big strength is its use as a mixing language and for gluing components, besides there can be additional benefits in inter

17、facing Python with native applications.There are number of language mixing utilities like f2py, Jython, Cython and extension and embedding tools like SWIG which can be used to interface with legacy applications.

20、n you need it).The best of both worlds: By mixing Python and languages like C/C+ we not only avoid “reinventing the wheel” but also get the high-performance of C, along with the benet of interpreted environments-rapid development.

21、acy Applications (4/6)Extending and Embedding PythonThere are two basic methods for integrating Python with legacy applications written in languages like C/C+.Extension writing which involves the creation of new Python modules. These modules provide access to underlying C/C+ functions and variables.

22、 This is the more general use case Embedding which allows C/C+ programs to access the Python interpreter and execute Embedding and Interfacing with Legacy Applications (5/6)Extension Building ToolsAutomated tools (e.g. SWIG, GRAD, bgen, etc.)Automatically generate Python interfaces from an interface
