First Steps

This section covers the basic usage of oofem python bindings. It covers the installation, consisting of generating the python bindings and demonstrates the basic usage.

Installation

Prerequisities

The pybind11 library is included as submodule inside oofem repository. To build oofem with python bindings requires python-dev or python3-dev packages to be installed.

Generate binding code

Configure oofem target to build python bindings

cd oofem.build
cmake path_to_oofem_git_repository -D USE_PYTHON_BINDINGS=ON
make

Building the above project will produce a binary module file that can be imported to Python.

Basic usage

In the previous section we have built the oofem python module. Assuming that the compiled module is located in the current directory, the following interactive Python session shows how to load and execute the example:

$ python3
Python 2.7.10 (default, Aug 22 2015, 20:33:39)
Python 3.6.8 (default, Oct  7 2019, 12:59:55)
[GCC 8.3.0] on linux
