Based on #1211 and trixi-framework/PointNeighbors.jl#165.

To-Do:

  • Interact structure-structure
  • Deformation gradient
  • Interact structure-structure with viscosity (not easy because of the branching inside current_velocity. Also, even when hacking current_velocity, I could not get a significant speedup with viscosity.)
