## Status:

succeeds

## Recommended resolution:

128x16x1 for dt=5e-3 for the current autotest.

## Comments:

A production run is (see also http://doi.org/10.5281/zenodo.18564321):
projects/Spreading/run_directories/DISKa8192g_rin01_H1f_D_Pa_rout1e3_alp05_e2em2_cs5_c002a/
where we use 8192x32x1 for a larger domain and dt=2e-3. Here we use: 128x16x1 for dt=5e-3.
