#2540: Unexpected Hamiltonian violation from Carpet boundaries, using CCZ4

 Reporter: KennethZen
   Status: new
Milestone: ET_2020_05
  Version: ET_2020_05
     Type: bug
 Priority: major
Component: Carpet

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
