This triggered a vlasiator crash in a 4 × 4 cell test run with 4 nodes, where space was subdivided into 1 × 4 cell strips. These were too small for the stencil size of 2. As an added bonus, this should speed up fsgrid setup for large simulations a little bit.

Let's wait with this one until the AMR dust settles in Vlasiator. |
