to Smuthi

Dear Smuthi Mailing List,

there is a new release of Smuthi: Version 2.2.4

It fixes the following bugs:

Wrong T-matrix calculations for layered particles in surrounding media with refractive index other than 1 (thanks to Tanay Paul for reporting this issue and to Krzysztof Czajkowski for fixing it).
Wrong simulation results for particles in lossy backgrounds (thanks to Christopher Gubbin for reporting this issue).
The API section of the online documentation was broken and is now fixed

The new release on PyPI includes a source distribution and binary wheels for Python versions 3.8 to 3.10.

Unfortunately, the usage of f2py for the NFMDS extension currently prohibits the installation of Smuthi with numpy versions 2.0 or later. It also seems not possible to install Smuthi with Python versions 3.11 or later.

Most people will have newer Python and/or Numpy versions. So it may be necessary to create an extra Python environment in which Smuthi works.
