Currently, running openEMS's example Python scripts on macOS always fails
with the following error:
$ python3 MSL_NotchFilter.py
Traceback (most recent call last):
File "/Users/gentoo/code/openEMS-Project/openEMS/python/Tutorials/MSL_NotchFilter.py", line 103, in <module>
FDTD.Run(Sim_Path, cleanup=True)
File "openEMS/openEMS.pyx", line 489, in openEMS.openEMS.openEMS.Run
AssertionError
This is caused by an oversight of an assertion in openEMS.pyx:
os.chdir(sim_path)
# ...
assert os.getcwd() == sim_path
The problem here is that "sim_path" is not a canonical path name,
so the assertion would fail if the path we're switching into contains
a symbolic link. This problem affects all operating systems, it's not
limited to macOS. But on macOS, the problem is especially serious,
since macOS's "/tmp" is a link to "/private/tmp" by default. Thus, it
causes an AssertionError in all the included Python examples.
Instead of doing "assert os.getcwd() == sim_path", we should write
"assert os.getcwd() == os.path.realpath(sim_path)" to ensure that
we're checking a canonical path.

openEMS python interface
Install
- Simple version:
python setup.py install
- Extended options, e.g. for custom install path at /opt/openEMS:
python setup.py build_ext -I/opt/openEMS/include -L/opt/openEMS/lib -R/opt/openEMS/lib"
python setup.py install
Note: The install command may require root on Linux, or add --user to install to ~/.local
