Re: [deal.II] Absorbing boundary conditions in different velocity domains still result in reflections.

  Thanks all. I need to simulate seismic wave propagation in media with different wave velocities, and step-24 is a great starting point. If seismic waves propagate through different velocity media,  I only modify the mass_matrix and boundary_matrix. However, there are still reflections occ

[deal.II] parallel periodic boundary conditions

2024-12-06 Thread Yann Jobic
Hello everybody, I have a working NS parallel solver, with AMR. It's working fine (i.e. good convergence rate of the error in L2 norm) with imposed velocity and outflow. I now need to use parallel periodic boundary conditions, with volumetric forces. I found that: 1) It's working perfectly
