Install

Instructions how to install the CSXCAD & openEMS python interface.

Linux

./update_openEMS.sh ~/opt/openEMS

  • Simple version (if installed to /usr/local):

cd CSXCAD
python setup.py install
cd ..

cd openEMS
python setup.py install
cd ..

  • Extended options, e.g. for custom install path at ~/opt/openEMS:

python setup.py build_ext -I/opt/include -L/opt/lib -R/opt/lib"
pyhton setup.py install

Note: The install command may require root on Linux, or add --user to install to ~/.local

Windows

The python interface for CSXCAD & openEMS requires a build with a MS Visual Compiler. Download the latest windows build with the “msvc” label: openEMS_win

Install Pre-build Modules

For some python versions, pre-build egg files can be found in the python sub-directory. E.g. for python 3.9:

cd C:\opt\openEMS\python
python -m easy_install CSXCAD-0.6.2-py3.9-win-amd64.egg
python -m easy_install openEMS-0.0.33-py3.9-win-amd64.egg

Build Modules From Source

Download the sources using git. Assuming the MSVC binary build of openEMS is install at “C:\opt\openEMS”, run from a working python command prompt (e.g. using WinPython):

git clone --recursive https://github.com/thliebig/openEMS-Project.git
cd openEMS-Project/CSXCAD/python
python setup.py build_ext -IC:\opt\openEMS\include -LC:\opt\openEMS
python setup.py install

cd ../../openEMS/python
python setup.py build_ext -IC:\opt\openEMS\include -LC:\opt\openEMS
python setup.py install

Setup

Important Note: Python needs to find the dependent libraries (dll’s) during module import. To allow this, it is necessary to set an environment variable (permantently):

setx OPENEMS_INSTALL_PATH C:\opt\openEMS
