Warning! SpinDynamica 3.6.x with Mathematica v13
Erroneous results have been reported when using SpinDynamica v3.6.x with Mathematica version 13.
This is very surprising behaviour since Mathematica should be backwards compatible.
This has been pinned down to a surprising inconsistency in the handling of SparseArray objects between Mathematica versions 12 and 13. A bug report has been submitted to wolfram.com.
SpinDynamica v3.7 includes a workaround for known symptoms,
All SpinDynamica users using Mathematica version 13 should upgrade to SpinDynamica v3.7 or later.

SpinDynamica administration
Welcome to Christian Bengs who has taken over administration over this site.
Christian has already done a lot of excellent coding as part of our new release of SpinDynamica (v3.0.1) and our first SpinDynamica publication. It’s great to have his help!
So many thanks to Christian, and enjoy the new version of SpinDynamica!

2D spectra
The attached code may be used for simple 2D simulations using SpinDynamica. It is not completely general but should do for many purposes. More general code will be included in SpinDynamica in future.
This example has also been posted on the forum, where you may also post responses.
