Unexpected Hamiltonian violation from Carpet boundaries, using CCZ4
Issue #2540
invalid
While using CCZ4 to simulate a single star, the Hamiltonian constraint violation initially came from the star surface as expected, but after some time, the violation was dominated by areas near corners of refinement levels (by Carpet) as shown in following figures, which were strange. Any suggestions?
Thanks and regards,
KZ

In the ET call from 2021-08-05 Peter reported on having looked further into this and it seems that the issue was eventually tracked down to missing dissipation setting in the parameter file.
Unless objected I will close this ticket as “resolved” after 2021-08-13.
