v2.2.0

[2.2.00] 2025-01-17

Changed

• Fix a bug that could lead to a segmentation fault when MHD+Fargo+MPI (with X3 domain decomposition) are all enabled (#295)
• Fix a bug that could result in an incorrect magnetic field when initialising B from the vector potential in non-axisymmetric spherical geometry (#293)
• Fix a bug that could result in Idefix believing the MPI library is not Cuda aware for some versions of OpenMPI (#310)
• Ensure that the behaviour in 1D Spherical geometry is identical to Pluto (#291)

Added

• Add the python interface "pydefix", allowing users to initialise and analyse Idefix simulations live from Python without writing any file (#277)
