Attention: i10git will shutdown soon!

This i10git GitLab server was migrated to gitos.rrze.fau.de due to hardware issues with the current host. This affects all production repositories, including waLBerla, lbmpy, pystencils and HyTeG.

Login: Gitos supports DFN-AAI and eduGAIN. If your institution does not support either, please use our GitHub mirrors.

Onboarding: All repositories belonging to groups were migrated. To regain access, first log in to gitos.rrze.fau.de once to activate your account. Then email cs10-admin@fau.de with your old i10git and your new gitos.rrze username (the @) as shown on your respective user profiles. We will reassign your accordingly. Note: Repositories from former courses (e.g. advpt) were not migrated.

Personal repositories in individual user namespaces were not migrated. Please export these yourself before the old server is shut down.

Expected shutdown by the end of 2026. Until then, the old i10git server will still be reachable with all repositories archived (read only). However, due to the ongoing hardware issues, it may remain unreliable and will receive no further maintenance.

The parent group is archived. This project and its data are read-only.
Segfault in LatticeBoltzmannStep with D3Q19 free-slip
When setting up a simulation with a free-slip boundary condition in `LatticeBoltzmannStep` with a D3Q19 stencil, there is a segmentation fault during the `run` command. Using a D2Q9 or D3Q27 stencil seems to work, as well as when the free-slip boundary condition is used outside of `LatticeBoltzmannStep`, i.e., by creating manually the data and boundary handling (as done in the free-slip test case). A non-working example is attached. [freeslip_d3q19_bug.py](/uploads/4e7a58a6fbc0ba5b1a7a40e01fa6767f/freeslip_d3q19_bug.py)
