Hey all,
I am working on the new synchronization in the presync branch, and there's
a scheduling comment I don't understand. On line 234 (master branch) of the
ADMBase schedule.ccl, the following comment is given before scheduling a sync
for ADM grid functions:
> For Mesh Refinement it is possible (eg Cowling approximation) that ADMBase
> variables will need synchronization even when not evolved (eg when a new
> refined grid appears)
According to this, a sync should be triggered in some cases at the mesh
refinement stage. Since I don't understand the reasons for this, I can't
reproduce this behavior in the new method. Why does the mesh refinement require
a sync only sometimes? Is there a specific scheduled subroutine which creates
this behavior, or is it inherent in the AMR process itself?
