<p>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?</p>
<p>Thanks and regards,</p>
