v4 v5 41 41 42 42 AMR prolongation and restriction operators maintain a divergence free magnetic field at multi-resolution boundaries in an AMR calculation. The operators constrain grid-edge magnetic field components on coarse levels following an area weighted average of finer levels. Multi-resolution simulation initialization must also satisfy this constraint. This is trivially satisfied for uniform initial magnetic fields, but ensuring non-linear initial field profiles maintain the contraint requires a fine-tuned startup procedure. 43
